Two Contemplation Models of Nāmamātra in the Yogācāra Literature

: This article contextualizes the meaning of nāmamātra in the Mahāyānasūtrālaṃkārabhāṣya and explores the history of modifications of this term in the Yogācāra literature. The term already exists in the pre‑Yogācāra literature, such as the Aṣṭasāhasrikā Prajñāpāramitā and the Bhavasaṃkrān‑ tisūtra , where it means name only. The chapter Bodhisattvabhūmi of the Yogācārabhūmi applies this meaning and explains how to interpret it to understand the true nature of the contemplative ob‑ ject; that is, what is named is nothing but a name, and what exists is the inexpressible thing ( vastu ). When people lack this understanding and regard for the expressed object as existent, they suffer subsequent afflictions and suffering. A similar but slightly modified explanation is also found in the Madhyāntavibhāgabhāṣya , where the author states that a single object has two intrinsic characteristics ( svalakṣaṇa s), the conventional and the ultimate, and that the former is expressed by a mere name and is non‑existent, while the latter is ineffable and existent. However, the Mahāyānasūtrālaṃkārabhāṣya and Sthiramati’s commentary on it, the *Sūtrālaṃkāravṛttibhāṣya , insert another meaning of nāmamā‑ tra : there are only mental factors. They also describe two contemplation phases, whereby practi‑ tioners should first understand the non‑existence of the expressed object before recollecting the term nāmarūpa in the context of the five constituents ( pañcaskandha ) and concluding that material and phys‑ ical factors ( rūpa ) do not exist; rather, only the mental factors do ( nāmamātra ). Finally, this second meaning of nāmamātra should be further contemplated, and the mere mental factors should also be regarded as ultimately non‑existent because the external objects causing them were already consid‑ ered non‑existent. This examination of various Yogācāra explanations of nāmamātra sheds light on the multiple phases of modifications of Buddhist terms that occurred in the Yogācāra literature dur‑ ing the systematization of Yogācāra contemplation.


Introduction
This article aims to explore the Yogācāra term nāmamātra ("name only").Previous studies have investigated multiple dimensions of Yogācāra terms, such as cittamātra ("mind only"), vijñaptimātra ("representation only"), and vijñānamātra ("consciousness only"). 1 In contrast to the detailed examination of these terms, however, the meaning of nāmamātra has been less explored, despite its significance for Yogācāra contemplative practice.
The term nāmamātra is found not only in the Yogācāra literature but also in the pre-Yogācāra literature.For instance, the Aṣ ṭ asāhasrikā Prajñāpāramitā (Aṣ ṭ ) uses nāmamātra and vyavahāramātra ("conventional expression only") as synonyms (Aṣ ṭ , p. 235). 2 The Bhavasaṃ krāntisūtra (BhSS) regards it as a synonym for saṃ jñāmātra ("word only"). 3Some early Yogācāra texts reflect a similar meaning of nāmamātra.In the chapter Bodhisattvabhūmi of the Yogācārabhūmi (BoBh), 4 for example, nāmamātra is used together with vastumātra ("thing only") and prajñaptimātra ("designation only") to explain the relationship between expressions and objects to which expressions are given. 5espite this earlier usage, by the time of Vasubandhu (fifth century CE) and Sthiramati (sixth century CE), at the latest, Yogācāra Buddhist texts seem to reflect an attempt to connect the term to the famous doctrine of vijñaptimātra ("representation only") or cittamātra ("mind only") and to use it in contemplative manuals.In the Mahāyānasūtrālaṃ kārab-hāṣ ya (MSABh), Vasubandhu equates nāmamātra with vijñaptimātra, 6 and, in the commentary of the MSABh, the *Sūtrālaṃ kāravṛ ttibhāṣ ya (SAVBh), Sthiramati considers it a synonym of cittamātra. 7These various meanings of nāmamātra in Yogācāra texts reveal several phases through which the Yogācāra explanation of nāmamātra passed before their contemplative manuals were established.I will therefore explore these phases and investigate how contemplation of nāmamātra was modified in the Yogācāra tradition.
Before examining the relevant Yogācāra texts and their multiple layers of interpretation, in Section 2, I will first investigate the Aṣ ṭ and BhSS to explore the earliest meaning of nāmamātra.In Section 3, I will turn to the BoBh, the earliest Yogācāra texts examined in this article, to show the first phase adopting the term nāmamātra for describing how to investigate the contemplative object for the sake of attaining correct knowledge.Here, understanding nāmamātra is described as essential for attaining the correct knowledge (yathābhūtaparijñā) that leads to the Mahāyāna version of parinirvāṇ a.This understanding is related to seeing two natures of a single object; that is, the practitioner is required to see the nonexistence of what is named and the existence of the inexpressible thing (vastu).Next, in Section 4, while examining the Madhyāntavibhāgabhāṣ ya (MAVBh), I will address the second phase of modification of nāmamātra in the Yogācāra tradition.The MAVBh also employs nāmamātra and explains two "intrinsic characteristics" (svalakṣ aṇ a) of a single object. 8he author of the MAVBh discriminates the conventional intrinsic characteristic expressed through names from the inexpressible intrinsic characteristic.Finally, in Section 5, I will examine a Yogācāra contemplation manual in the MSABh, which expands on and elaborates nāmamātra in more detail.In the SAVBh, Sthiramati introduces two different meanings of nāmamātra; that is, "name only" and "mental factors only".He does not explain why the meaning of nāmamātra should be changed in the course of contemplation but simply states that it is changed.He also states that those who reach the first stage of Bodhisattva (*prathamabhūmi) do not consider even mental factors (nāman) existent.His explanation provides an example that reflects how terms were adopted and reinterpreted in the course of systematizing Yogācāra contemplation manuals.

The Meaning of Nāmamātra in the Aṣ ṭ asāhasrikā Prajñāpāramitā and the Bhavasaṃ krāntisūtra
The Aṣ ṭ provides a hint that helps us understand the early Mahāyāna Buddhist's definition of the term nāmamātra.This term is used together with vyavahāramātra as follows: The perfection of wisdom is to be approached in the sense that all phenomena/factors (dharmas) are spoken about through mere names (nāmamātra), mere conventional expressions (vyavahāramātra).The conventional expression, moreover, is neither anyplace nor from someplace, nor is the conventional expression anything. 9rvadharmāś ca nāmamātreṇ a vyavahāramātreṇ ābhilapyante iti prajñāpāramitā anugantavyā.vyavahāraś ca na kvacin na kutaścin na kaścid vyavahāraḥ .(Aṣ ṭ , p. 235) The meaning of "mere name" (nāmamātra) could be inferred from its elaboration as "mere conventional expression" (vyavahāramātra).Although linguistic conventions express phenomena, the author explains that the conventional expression neither refers to nor arises from anything, nor is the conventional expression itself anything.Therefore, the phrase "mere conventional expression" in the Aṣ ṭ implies that there are the expressed phenomena (dharmas) and the act of expressing, but the latter arises from mere conventional expression that is neither based on anything existent nor is itself existent.Likewise, the compound "mere name" would mean that there is the linguistic convention of expressing something by using mere names, which are neither based on anything existent nor are themselves existent.
Here, the negation na requires further investigation.Conze suggests, 10 for example, that the brief phrase "na kaścid vyavahāraḥ " should be understood as "the conventional expression is not itself anything real".This translation still leads us to wonder what "real" means in this context and how it could be differentiated from anything unreal.One possible explanation is to interpret non-existent or unreal as existing mentally.This interpretation can be found in the BhSS, which applies the term nāmamātra after providing a Mahāyāna description of the rebirth process. 11This text contains a dialogue between the Blessed One or the Buddha and the King Bimbisāra, in which the King questions how karma and rebirth are possible if all conditioned factors (sarvasaṃ skāra) are empty: How, O Blessed One, does karma, though having been performed, amassed, and long ceased, appear again to the mind at the moment when the time of death is approaching?Or, when all the conditioned factors are empty, how are karmas known not to disappear?kathaṃ bhagavan kṛ topacitasya karmaṇ aś ciraniruddhasya maraṇ akālasamaye pratyupasthite punar manasaḥ sammukhībhāvo bhavati.kathaṃ vā śūnyeṣ u sarvasaṃ skāreṣ u karmaṇ ām avipraṇ āśaḥ prajñāyate.(BhSS, pp.418-19)   Although the King does not elaborate on what emptiness means and why he thinks the empty conditioned factors would not justify karma not disappearing entirely but appearing again, we can find further details in the reply of the Blessed One, who states: "The last consciousness is empty of the last consciousness, the death is empty of the death, the first consciousness is empty of the first consciousness, the birth is empty of the birth". 12he empty and conditioned factors are represented by the last consciousness up to birth, whereby the subsequent arising and ceasing could be considered the process of rebirth.Thus, examining the description of these factors would help us understand how the characteristics of the empty conditioned factors and the process of rebirth are described and justified in this text.Moreover, this description is summarized by verses in which the term nāmamātra is adopted.Examining the dialogue between the King and the Buddha therefore helps us understand how nāmamātra is defined and what "non-existent expressions" means in the BhSS.
The Buddha's answer reflects a Buddhist thought that defines karmas and factors involved in the process of rebirth as mental factors.To explain this, the BhSS begins with the metaphor of a dream: For example, Great King, a sleeping man would have sex with the most beautiful woman in the country in his dream.He who awakened from sleep might remember the most beautiful woman in the country.How do you think of this, Great King, does the most beautiful [woman] in the country in the dream exist?tadyathā mahārāja śayitaḥ puruṣ aḥ svapnāntare janapadakalyāṇ yā striyā sārdhaṃ paricaret.sa śayitavibuddhas tāṃ janapadakalyāṇ īṃ striyam anusmaret.tat kiṃ manyase mahārāja saṃ vidyate sā janapadakalyāṇ ī svapnāntare.(BhSS, pp.420-23) The beautiful woman indeed exists as a mental entity because she appears to the mind of the dreamer; however, the King agrees that she does not exist, 13 which suggests the phrase "she exists" (saṃ vidyate) means as a physical entity in the external world.The Buddha emphasizes that it is not wise to think that this woman exists in this external world and to search for her on waking.The Buddha also explains that this mere non-existent mental object can make the foolish person generate continuous and momentary actions or karmas not only in the dream, such as seeing and having sex with her, but also after the dream, such as remembering and searching for her.Even though this dream woman does not exist as a real entity in the external world, karmas resulting from this woman arise consecutively.
The BhSS continues to explain that the arising and ceasing of karmas and the process of rebirth in our lives can be likewise explained: The foolish and unlearned ordinary person sees visible objects (rūpa) with eyes and becomes attached to states of delight and dejection.Being attached, he becomes affected.Being affected, he becomes enamored.Being enamored, he enacts the karmas generated through desire, hatred, and ignorance, by body, speech, and mind.However, this enacted karma ceases in the mind.Upon ceasing, it does not remain in the eastern region, nor in the southern region, nor in the western, nor in the northern, nor above, nor below, nor in any intermediate region.
Because the karma homogeneous to this [realm] wanes when the moment of dying is near, that karma [re]appears to the mind when the last consciousness ceases, like the most beautiful woman in the country [reappears] to [the mind of] the person awakened from sleep.Thus, Great King, the consciousness belonging to the last existence ceases, and the first consciousness which partakes in birth arises, either among gods, human beings, semi-gods, hell dwellers, animals, or ghosts.kālāntareṇ a maraṇ akālasamaye pratyupasthite tatsabhāgasya karmaṇ aḥ kṣ ayāc caramavijñāne nirudhyamāṇ e manasas tat karmāmukhībhavati, tadyathā śayitavibuddhasya puruṣ asya janapadakalyāṇ ī strī.iti hi mahārāja caramabhavikaṃ vijñānaṃ nirudhyate, prathamavijñānam aupapattyaṃ śikam utpadyate yadi vā devesu yadi vā manuṣ yeṣ u yadi vāsureṣ u yadi vā nirayeṣ u yadi vā tiryakṣ u yadi vā preteṣ u. (BhSS, pp.428-31) The reappearance of a karma to the mind is compared to the reappearance of the dream woman to the mind of the person awakened from sleep.The cessation of the last consciousness could be naturally comparable to the end of the dream.Just as the dream woman, who does not exist in the external world, can generate another action even beyond the dream, the karma that re-arises in the mind can make another consciousness arise, which is the first consciousness of the next life.Like the woman, this karma and all forms of consciousness do not "exist" physically in this world, but this flow of mental events can still work and enable the rebirth.
This exposition is summarized by seven verses, the first of which includes the term nāmamātra: All this which is nothing but name is established only in designation; 14 separated from the expression, that which is expressed does not exist.
nāmamātram idaṃ sarvaṃ saṃ jñāmātre pratiṣ ṭ hitam; abhidhānāt pṛ thagbhūtam abhidheyaṃ na vidyate.(BhSS, p. 438) According to this verse, everything that is expressed, such as "the last consciousness", does not exist.Based on the previous dialogue, the meaning of "existence" in this verse would be understood as existence in the external world.Likewise, the phrase "that which is expressed does not exist" (abhidheyaṃ na vidyate) would mean that what is expressed does exist in the external world because it is something "established" in names and designations, and thus, they are mental or conceptual.
As seen at the beginning of this section, the Aṣ ṭ briefly describes all dharmas as expressed by mere expressions that are neither based on anything in existence nor are themselves existent.The Aṣ ṭ does not explain what non-existence or real means and how nonexistent names can express something.Contrary to this, the BhSS specifies the meaning of existence as existence in the external world; karmas (e.g., the dream woman) and dharmas (e.g., the last consciousness) expressed by mere names are described not as existing in the external world independently from the expression but as existing as mental or conceptual entities.According to this interpretation, the meaning of "name only" could be understood as follows: names do not exist in the external world, nor do objects expressed by these names.
This explanation in the BhSS seems to have led to philosophical discussion about inexpressible things, which is preserved in the later commentary literature.There, debate arises as to whether there are (1) inexpressible things or not and (2), if there are, whether they exist in the external world or simply in the mind.The BhSS itself does not clearly state a perspective and this has left room for various interpretations. 15owever, the contemplative model that the BhSS proposes is relatively clear.Like the man who seeks the dream woman after awakening, foolish and ordinary people do not understand that the karmas they made do not remain in the external world but cease and rearise in the mind.They do not regard all these karmas expressed by mere names (nāmamātra) as mere mental entities, and this erroneous thought leads to continuous karmas and, in the end, rebirth.
The usage of nāmamātra in the BhSS focuses on explaining the non-existence of names and objects expressed by names.The BoBh, which will be examined in the following section, combines nāmamātra with vastumātra and prajñaptimātra and explains not only the non-existence of names and objects expressed by names but also the existence of the ineffable thing.The contemplation model described in the BoBh also focuses on observing both the existence of a name and the non-existence of an ineffable thing.

The Description of Understanding Nāmamātra in the Bodhisattvabhūmi
In the BoBh, nāmamātra is described as the contents to be investigated (paryeṣ aṇ ā) and the methods to attain the right knowledge (parijñāna) of reality (tattva).The BoBh describes four kinds of investigation, which result in four kinds of correct knowledge (yathābhūtaparijñā): the investigation of a name (nāman), a thing (vastu), that which is designated as the intrinsic nature (svabhāvaprajñapti), and that which is designated as the particularity (viśeṣ aprajñapti). 16The investigation of a name (nāmaparyeṣ aṇ ā) consists in seeing it only with regard to the name (nāmni nāmamātraṃ paśyati). 17By means of this observation, the Bodhisattva attains the correct knowledge about a name.That is, a name is the cause of ideation (saṃ jñā), superimposition (samāropa), clinging (abhiniveśa), and speaking (abhilāpa).If a name would be not given to a thing (vastu), any ideation does not arise.The BoBh explains this as follows: If, for a thing ordinarily conceived of as rūpa, etc., a name "rūpa" is not decided upon, no one would thus conceive that thing a rūpa; and not conceiving it, one would not superimpose or cling to it.And not clinging to it, one could not speak about it.Thus, one knows it precisely, in detail.This is said to be knowing the investigated name precisely, in detail. 18di rūpādisaṃ jñake vastuni rūpam iti nāma na vyavasthāpyeta na kañcit tad vastu rūpam ity 19 evaṃ saṃ jānīyāt.asaṃ jānan samāropato nābhiniveśeta.an-abhiniveśaṃ nābhilapet.iti yadevaṃ yathābhūtaṃ prajānāti.idam ucyate nā-maiṣ aṇ āgataṃ yathābhūtaparijñānam. (BoBh D , pp. 36-37; BoBh W , p. 53) The BoBh differentiates a name from a thing (vastu).The thing itself does not cause any ideation; it is the name that is given to that thing and causes ideation, etc.This observation of name only is followed by the observation of thing only (vastumātra); specifically, the BoBh subsequently explains that the Bodhisattva should observe thing only (vastumātratā) with regard to the thing in order to attain the second correct knowledge.Observing only the thing itself is described as resulting in seeing the thing that is ineffable (nirabhilāpya) and not associated with all the the speech (sarvābhilāpaviśliṣ ṭ a).The Bodhisattvas attaining this knowledge would not identify the thing itself with what is named. 20his contemplation of a name and a thing is followed by observing that which is designated as the intrinsic nature and the particularity.A given thing could arise as having the nature of rūpa.Again, the thing itself exists, but it does not exist as having this nature.There is "only the mere semblance" (ābhāsatā) of an intrinsic nature, and thus, the Bodhisattva sees this designated intrinsic nature as "a magical creation, a reflected image, an echo, a hallucination, the moon's reflection in the waters, a dream and an illusion". 21n this context, particularity refers to the specific quality of objects, with existence (bhāva) and non-existence (abhāva) given as examples.The BoBh states that the given thing could be designated as having either of these two particularities; that is, it could be designated as non-existent (abhāva) in that it is not "perfected" (pariniṣ pannatva) through the nature expressed by names 22 , but it could also be designated as existent (bhāva) in that it is determined to have an ineffable nature. 23ere, we can find a dynamic contemplation of a meditative object.The BoBh requires practitioners to see two natures of a contemplative object.Its nature, as expressed by language, should be regarded as non-existent and like a dream.This nature is understood by means of observing nāmamātratā and the part of prajñaptimātratā.However, there is the ineffable nature of a contemplative object, and practitioners should understand the thing itself exists with the ineffable nature separated from the name.This second nature is understood through observing vastumātratā and another part of prajñaptimātratā.Ordinary people cannot differentiate between these two natures and, thus, are confused between the truth of existence and non-existence.This confusion generates various sufferings.Contrary to this, those who attain all these forms of correct knowledge reach the complete nirvāṇ a (parinirvāṇ a) of the great vehicle because all proliferation (prapañca) ceases. 24

Two Intrinsic Characteristics and Nāmamātra in the Madhyāntavibhāgabhāṣ ya
The MAVBh offers a similar explanation to the BoBh, but the wording is slightly different.This text suggests two different intrinsic characteristics (svalakṣ aṇ as) of the same object.In a brief verse of the MAVBh, the truth of nāmamātra is stated as follows: Everything is [said to] be the mere name in order for all the imagination not to arise.
svalakṣ aṇ e 'viparyāsaḥ , paramārthe svalakṣ aṇ e. (MAVBh, p. 67 [MAVBh 5.18]) The following auto-commentary elaborates that the word "everything" (sarva) is defined as the sense faculty of seeing (cakṣ us), the visible object (rūpa) up to the mind (manas), and the object of the mind (dharma); that is, twelve elements (āyatana).Understanding (jñāna) all these elements as mere names is considered non-erroneous (aviparyāsa) about the ultimate intrinsic characteristic because this understanding is the antidote against all kinds of imagination (vikalpa). 25he ultimate intrinsic characteristic is explained by Sthiramati's commentary, the Mad-hyāntavibhāgaṭ īkā (MAVṬ ), 26 which regards it as inexpressible (anabhilāpyatva; MAVṬ , p. 221).Although, differently from the BoBh of the YoBh, the MAVBh does not use the term "thing" (vastu) but applies the term "intrinsic characteristic", this text still provides a similar model of the contemplation process.Those contemplating should understand two intrinsic characteristics of an object.They should regard conventionally defined objects (jñeya), whose intrinsic nature (svabhāva) is expressed as the sense faculty of seeing, etc., as non-existent and as mere names (nāmamātra). 27This understanding should be combined with the nonerroneous understanding of the inexpressible ultimate intrinsic characteristic of the same object.In other words, the non-existence of the conventional intrinsic characteristic does not mean the complete non-existence of the object in all respects but the existence of the ultimate intrinsic characteristic, and this understanding can be attained by means of contemplating the doctrine of name only (nāmamātra).
Despite some variations, the BoBh and MAVBh reflect a similar application of the term nāmamātra concerning Yogācāra contemplation: Contemplating the doctrine of the 2024, 15, 600 7 of 12 nāmamātra leads to understanding two different natures of an object: the non-existence of the expressed nature and the true existence of the inexpressible nature.This understanding is described as essential for the cessation of all imagination.
However, contemplating nāmamātra is not limited to thinking about language and the relationship between the expression and the expressed object.In the Yogācāra literature, some texts define nāman as mental factors-including those ranging from feeling (vedanā) up to consciousness (vijñāna)-which are opposed to material factors (rūpa).In this usage, the meaning of nāmamātra is changed to "only mental factors exist", and nāmamātra is explained not as a doctrine for understanding the non-existence of the expressed nature and the existence of the inexpressible nature of an object but as a doctrine leading to thinking about the non-existence of material/physical factors.The MSABh reflects this usage, which will be examined in the following section.

Two Meanings of Nāmamātra in the Mahāyānasūtrālaṃ kārabhāṣ ya
In MSABh 11.48, nāmamātra is used to explain a kind of "liberation" (vimukti).This verse uses the word nāmamātra three times.Below, I translate the verse reflecting commentaries before examining the commentaries in more detail: When from the collection (saṃ bhāra), there are base (ādhāra) and product (ādhāna), one sees nāmamātra.In seeing this [nāmamātra], one sees [another meaning of] nāmamātra.Afterwards, moreover, one does not see even that [nāmamātra]. 28hāre saṃ bhārād ādhāne sati hi nāmamātraṃ paśyan paśyati hi nāmamātraṃ tatpaśyaṃ s tac ca naiva paśyati bhūyaḥ .(MSABh, p. 67) The verse indicates two dimensions of contemplating nāmamātra.The practitioner is required to observe nāmamātra at first but should not see it in the end.The following autocommentary explains that base, collection, and product mean hearing (śruti), accumulating [merits] previously (pūrvasaṃ bhāralābha), and contemplating correctly (yoniśomanaskāra), respectively. 29he SAVBh, Sthiramati's commentary, helps us understand how these terms were interpreted in ancient India in the sixth century CE.Hearing indicates hearing and thinking about the supreme teaching taught by the virtuous friend (*kalyāṇ amitra); 30 the collection refers to the accumulation of merit in previous lives over one countless eon on the level of devoted conduct (*adhimukticaryābhūmi); 31 and the product means contemplating all dharmas as impermanent, suffering, empty, and selfless on the levels of devoted conduct. 32The first part of this verse explains that accumulating merits, hearing teachings, and contemplating dharmas are needed before observing the doctrine of nāmamātra correctly.
Sthiramati continues to explain that nāmamātra is observed by those are at the stage of practicing four wholesome roots (*kuśalamūla), that is, subdivisions ("heat", "summit", "acceptance", and "the highest ordinary stage") of the Mahāyāna path of preparation for reaching the first Bodhisattva stage. 33Among these four stages, the practitioner sees the name only at the first and second stages; that is, the "heat" (*uṣ magata) and the "summit" (*mūrdhan). 34Through this observation, the practitioner perceives the non-existence of the intrinsic nature of factors (chos rnams kyi rang bzhin yod pa ma yin par mthong).Sthiramati explains these stages as follows: At the stage of the "heat" and the "summit", one sees all factors (dharmas) as mere names (*nāmamātra, ming tsam).They see them as mere words (*padamātra, tshig tsam), mere talks (*abhilāpamātra, brjod pa tsam), mere conventional expressions (*vyavahāramātra, tha snyad tsam), and mere imaginings (*vikalpamātra, rnam par rtog pa), and see thereby the non-existence of the intrinsic nature of factors.drod dang rtse mo'i tshe na chos thams cad ming tsam du mthong bar'gyur te/tshig tsam brjod pa tsam tha snyad tsam rnam par rtog pa tsam du zad par mthong gis chos rnams kyi rang bzhin yod pa ma yin par mthong ngo.(SAVBh II, p. 117) This explanation reflects the contemplation of nāmamātra, which is similarly described in the BoBh and MAVBh, as examined above in Section 4.
However, we can also find a simplification of the contemplation.Sthiramati does not distinguish between a thing (vastu) and a name (nāman), as in the BoBh, or between the ultimate and conventional intrinsic characteristics, as in the MAVBh.While these two texts describe contemplating nāmamātra as the way to lead practitioners to understand the non-existence of what is expressed by name and the existence of the inexpressible thing, Sthiramati simply explains observing nāmamātra as perceiving the non-existence of an intrinsic nature.
Sthiramati continues by explaining how to investigate nāmamātra further.Contrary to the BoBh and MAVBh, he regards nāmamātra as having two different meanings and interprets observing nāmamātra in the third stage, the "acceptance" (*kṣ anti), as perceiving the non-existence of material constituents (rūpa); that is, nāmamātra is interpreted as the doctrine of mental constituents only: Afterwards, in the stage of "acceptance", one sees all factors as nothing but the mind (*cittamātra, sems tsam).Only four mental constituents [are seen], and the constituents (*dharma, chos) that do not belong to those [four], including "visual object" (*rūpa, gzugs), etc., are not seen.Therefore, one sees [them] as the nameonly (*nāmamātra, ming tsam) because the object to be grasped is abandoned.de'i 'og tu bzod pa'i dus na chos thams cad sems tsam du mthong ste / ming gi phung po bzhi tsam du zad kyi de las ma gtogs pa'i gzugs la sogs pa'i chos gang yang ma mthongs bas na ming tsam du mthong ba zhe bya ste / gzung ba rnams de'i tshe spangs pa'i phyir ro.(SAVBh II, p. 117) Nāmamātra is equated to vijñaptimātra (representation only) by Vasubandhu (MSABh, p. 67) and to cittamātra (mind only) by Sthiramati. 35Previous research has shown that in the Buddhist literature, nāmarūpa has been explained as five psycho-physical constituents (pañcaskandha); material factors (rūpa), feeling (vedāna), ideation (saṃ jñā), impulse (saṃ skāra), and perception (vijñāna). 36Except rūpa, the other four constituents are often denominated as nāman, non-material factors. 37Therefore, Sthiramati's interpretation of nāmamātra as "non-material factors only" could be supported by Buddhist texts, although he does not mention any textual grounds for his interpretation.
However, the equation of nāmamātra with cittamātra diverges from the description of nāmamātra in the BoBh and MAVBh, which do not state the non-existence of material constituents but rather focus on explaining the non-existence of what is named and the existence of the inexpressible thing (the BoBh) or the inexpressible ultimate characteristic (the MAVBh).Contrary to this, the MSABh uses this term not to distinguish between the expressed thing and the ineffable thing but to classify various traditional constituents into two groups: the non-existent material factors (rūpa) and the existent but non-material factors (nāman).
Sthiramati also describes "the highest ordinary stage".Those who are at this stage are described as no longer perceiving "mental factors only"; in other words, they regard even non-material constituents as non-existent.This stage is obtained by understanding the non-duality of agent and object.This practice is described as not seeing nāmamātra: After that [stage], at the highest ordinary stage (*laukikāgradharma, 'jig rten gyi chos mchog), what is seen as nāmamātra at the stage of "acceptance" is not seen [anymore] because the grasping at the existence as mind-only is also given up at this stage.This is because it is understood as being not suitable to say that [the object] grasped does not exist, but the grasping perception does exist.de nas 'jig rten gyi chos mchog gi dus na bzod pa'i tshe ming tsam du mthong ba de yang ma mthong ste/sems tsam du yod par 'dzin pa yang de'i tshe spangs pa'i phyir te/gzung ba med pa yang 'dzin pa yod par mi rigs par khong du chud pa'i pyir ro.(SAVBh II, p. 118) Those who are at this stage are described as contemplating the distinction between the object to be grasped (*gṛ āhya, gzung ba) and the grasping (*grāhaka, 'dzin pa) perception.The non-existence of the material constituents is equated to the non-existence of objects to be grasped by the mind.According to the passage, if all external objects are considered non-existent, it is impossible to defend the claim that the grasping perception caused by external objects exists.Sthiramati explains that this reasoning leads to the conclusion that there is neither a cognized object nor a cognizing agent.This knowledge (jñāna) of nonduality is explained as leading the practitioner to the first stage of Bodhisattva. 38his systematization of the contemplation model in the MSABh, or in Sthiramati's commentary at the latest, sacrifices the established meaning of nāmamātra and requires two layers of interpretation: the practitioner perceives nāmamātra first as "name only" and second as "mental factors only".However, this practice has the advantage of attaining two kinds of knowledge: 1.
Practitioners have a chance to think about the relationship between a name and an object to which a name is given and to conclude that what is named does not exist.2.
By thinking about another meaning of nāmamātra-that is, that only the four mental constituents exist, except the material constituents (rūpa)-the practitioner abandons attachment to external and material constituents.

Through contemplating the nature of perception and understanding the impossibility of any mental phenomena without objects to be grasped by the mind, the practitioner attains the knowledge of the non-existence of mental constituents.
This contemplation model is different from that described in the BoBh and MAVBh.The MSABh and its commentary apply two meanings of nāmamātra to make practitioners continuously negate various kinds of existence.Unlike the BoBh and MAVBh, understanding existence of the ineffable thing is not mentioned in describing contemplation of nāmamātra in the MSABh.Moreover, the doctrine of nāmamātra is explained as what should be abandoned before reaching the first stage of Bodhisattva.

Concluding Remarks
Examining nāmamātra in the Yogācāra literature demonstrates that this term has been modified according to the contemplation models provided by each text.The BoBh exclusively focuses on describing the relationship between a name and a named thing, while observing nāmamātra leads practitioners to regard the expressed object as non-existent and to consider the ineffable thing existent.The MAVBh provides a similar description, but this text also reflects Yogācāra's striving to unify various terms into a single word; that is, the MAVBh uses the single term "intrinsic characteristic" (svalakṣ aṇ a) to distinguish between what is non-existent and what is existent.According to this explanation, a single object has a conventional intrinsic characteristic, which is expressed by names and is non-existent, and an ultimate intrinsic characteristic, which is ineffable and existent.The MSABh still uses nāmamātra to explain the nature of language, but understanding the nature of language through contemplating nāmamātra is described as a first step toward reaching the first stage of Bodhisattva.The MSABh then inserts a new definition of nāmamātra and uses it to establish a gradual practice.That is, nāman is redefined as the non-material factor that is opposed to the material factor (rūpa), and thus, nāmamātra means that only mental factors exist-not material ones.Those who observe this nāmamātra regard material factors as non-existent.After that, those who are at the highest mundane stage abandon even the doctrine of nāmamātra, and thus, they also regard mental factors as non-existent.To establish this gradual practice, the MSABh uses the term nāmamātra in two different senses.
In summary, the insertion or modification of nāmamātra stands as an example of modifying the meaning of traditional Buddhist terms to align with the philosophical and meditative perspective expressed in Yogācāra texts.Moreover, this modification did not happen just once but continuously, as I have shown by comparing the passages in the BoBh, MAVBh, and MSABh.The BoBh reflects the first phase in which the traditional term was applied to describe Yogācāra practice.In the MAVBh, we witness various terms summa-rized into a single word: intrinsic characteristic (svalakṣ aṇ a).The MSABh reveals the third phase, where the established meaning of the term is inserted or changed when it is needed for systemizing Yogācāra contemplation manuals.
