Editing Laṅkāvatāra Sūtra (section)

==Overview and main themes==
[[file:UG-LK Photowalk - 2018-03-24 - Maskeliya Reservoir (3).jpg|thumb|350px|Mount Malaya (also known as [[Adam's Peak|Sri Pada]]), [[Sri Lanka]], the main setting of the sutra.]]

Various scholars like [[D. T. Suzuki|DT Suzuki]] and Takasaki Jikido have noted that the text is somewhat unsystematic and disorganized, resembling the [[notebook]] or [[commonplace book]] of a Mahayana master which recorded important teachings.<ref>Karl-Heinz Golzio (2010). ''Lankavatara-Sutra: die makellose Wahrheit erschauen,'' pp 1-4. Barth.</ref><ref name=":1">Takasaki, Jikido (1980).

In Search of its Original Form]'', Indianisme et Bouddhisme : Mélanges offerts à Mgr Etienne Lamotte, Universite Catholique de Louvain, Institut Orientaliste.</ref> According to Takasaki Jikido, the Lanka "is, as often said, merely a mosaic collection of small parts put at random within the frame of a sutra."<ref name=":1" /> 

The present Sanskrit edition contains ten chapters and most scholars consider the introductory chapter (the "Ravana" chapter), the ninth chapter (a [[dharani]]) and the last chapter (the ''Sagathakam'' verses) as being later additions. Furthermore, not all versions of the sutra contain these chapters (1, 9, 10).<ref name=":1" /> However, some verses found in the ''Sagathakam'' are also duplicates and are found within the main body of the sutra. Takasaki Jikido has argued that these verse portions might actually be the earliest core of the sutra, around which prose explanations grew.<ref name=":1" />   

The ''Laṅkāvatāra Sūtra'' draws on and explains numerous important Mahayana Buddhist concepts including the philosophy of [[Yogachara|Yogācāra]] school, the doctrine of [[Śūnyatā|emptiness]] (''śūnyatā''), and the doctrines of [[buddha-nature]] (''tathāgatagarbha''), and the [[luminous mind]] (''prabhāsvaracitta'').<ref name=":0" /><ref>Youru Wang, ''Linguistic Strategies in Daoist Zhuangzi and Chan Buddhism: The Other Way of Speaking.'' Routledge, 2003, page 58.</ref> In the introduction to the sutra (the ''[[nidana]]''), the sutra outlines some key teachings which will be expounded on, "the Five Dharmas and the Three Inherent Natures (pañcadharmasvabhāva), the Eight Consciousnesses (vijñāna) and the Two forms of Selflessness (nairātmyādvaya)."<ref name=":11" /> Indeed, the sutra later states that within this set of teachings is included "all of the [[Mahayana]]".<ref name=":11" />  

According to Nguyen Dac Sy, the most important doctrines of the Laṅkāvatāra are the primacy of consciousness (Skt. ''[[Vijñānavāda|vijñānavada]]''), the teaching that consciousness as the only reality and that "all the objects of the world, and the names and forms of experience, are manifestations of the mind" as well as the "identification of the Buddha-nature (in the state of ''[[Buddha-nature|tathāgatagarbha]]'') with ''[[Eight Consciousnesses|alayavijñāna]]".<ref name=":3" />''

Other topics discussed in the sutra include [[Buddhist vegetarianism]], the theory of [[Icchantika|icchantikas]], the wrong views of non-buddhists ([[Tirthika|tirthikas]], especially [[Samkhya]]), a critique of the [[Śrāvakayāna|sravakayana]], the limited nature of [[language]] in describing the ultimate truth, the [[Ekayāna|One Vehicle]], the [[Bodhisattva|bodhisattva path]], and the three bodies of the Buddha ([[trikaya]]) doctrine.<ref name=":3" /><ref name=":0" /><ref name=":6" />      

=== Svacittamātra ===
{{MahayanaBuddhism}}
The ''Laṅkāvatāra Sūtra'' often presents a mind-only philosophy influenced by the idealistic thought of the [[Yogachara|Yogacara]] school. According to the ''Laṅkāvatāra Sūtra'' "all things are only manifestations of the mind itself" i.e. all phenomena are "mind-only" (''cittamātra'') or "ideation-only" (''vijñaptimatra'').<ref name=":4">Goddard, Dwight  (1932). A Buddhist Bible ([http://www.sacred-texts.com/bud/bb/bb14.htm Lankavatara sutra, chapter VII]), 1st edition; pp.110–111</ref> This idealistic view is explained by the ''Lanka'' as the view that "what is seen as something external is nothing but one's own mind" (''svacitta-drsya-mātram'')."<ref name=":6">Gishin Tokiwa. ''Lankavatara Sutram. A Jewel Scripture of Mahayana Thought and Practice. A study of the Four-Fascicle Lankavatara Ratna Sutram'', p. xl. [[Hanazono University]], Kyoto. Printed by the Meibunsha Printing Co. Lts., Kyoto, Japan, 2003.</ref> According to Gishin Tokiwa, this is not to say that there are no independent external beings conventionally, but rather what it means is that true insight into the nature of reality goes beyond all concepts of internal and external.<ref name=":6" /> Gishin Tokiwa sees the theory of ''svacittamātra'' as the central message of the sutra.<ref name=":9">Gishin Tokiwa, "Svacittamatra, the basic standpoint of the Lankavatara Sutra." Journal of Indian and Buddhist Studies 26.1, 1977, 34-39 137.1.34.</ref> 

The sutra often presents Yogacara theories of consciousness, like the eight consciousnesses and the three natures, as well as the "five dharmas".<ref name=":13">Ehman, Mark A. ''The Lankavatara Sutra'' in Charles S. Prebish (ed.) Buddhism: A Modern Perspective, Penn State Press, pp. 112-114, 2010.</ref> Furthermore, since, as the sutra states, the whole world "is nothing but a complex manifestation of one's mental activities," all phenomena are empty of self (''[[Anattā|anatman]]'') and illusory (''[[Maya (religion)|maya]]'') - "to be regarded as forms seen in a vision and a dream, empty of substance, unborn and without self-nature."<ref name=":4" />

Tokiwa further writes that the ''Laṅkāvatāra,'' being closely influenced by [[Prajnaparamita|Prajñaparamita]] thought, also tempers this idealistic mind-only view with the idea that ultimate reality transcends being and non-being (bhāvābhāva), and is beyond all views and concepts, even that of "mind" ([[Chitta (Buddhism)|citta]]) itself. Thus, even though the Lanka presents a "mind-only" view in some passages, other sections state that the [[Paramārtha-satya|ultimate truth]] or [[Tathātā|Suchness]] transcends even mind, thought, discrimination and subjectivity itself.<ref name=":9" /> Furthermore, the reason why all things are beyond being and non-being is closely connected to the idea that all experiences are mind only.<ref name=":9" /> It is because all experiences are just reflections of the mind of those deluded beings which experience them that we can say that phenomena have no single characteristic or way of existing. All things are experienced (or not experienced) in various ways (vaicitryam) by different types of living beings, but none of these experiences are fixed or ultimately true, each one is mistaken (bhranti) in some way.<ref name=":9" /> At the same time, we can say that this ultimate nature of the emptiness of all characteristics is something that does not change.<ref name=":9" /> This ultimate reality, the [[Dharmakāya|dharmakaya]], is also free from arising, abiding and cessation while also being the ground for the illusory manifestation of the world.<ref name=":9" /> 

In spite of this however, the view of "mind-only" is still seen as an important way to transcend our current deluded state, as the Lanka sutra states:<blockquote>Through attaining the reality as nothing but our own mind, which is the Self free from manifestation, we return to abiding in the final attainment of [[Prajñā (Buddhism)|prajña]].<ref name=":9" /> </blockquote>In turn, the view that the world and phenomena exist "externally", outside of mind, is seen as a serious error that leads to delusion and suffering. The Lanka sutra specifically cites the [[Mind–body dualism|dualistic]] view of [[Samkhya]] philosophy for criticism.<ref name=":9" />

=== The Five Dharmas ===
According to Saganuma, the schema of the Five Dharmas (pañcadharma), which explains all of reality in terms of five phenomena, is essential for understanding the basic worldview of the ''Laṅkāvatāra''. Indeed, according to Saganuma, the ''Laṅkāvatāra'' considers that all Mahayana teachings are included within these five dharmas.<ref name=":11" /> 

The Five Dharmas are the following:<ref name=":13" /><ref name=":11" /><ref>Suzuki, D.T. (1999). ''The Laṅkāvatāra Sūtra: A Mahāyāna Text'', Introduction, pp. xxxv-xxxvi. Motilal Banarsidass Publ.</ref> 

* Nimitta (images, appearances), this is what has characteristics like form (rupa), shape, distinctive features, and images (ākāra).
* Nāma (naming), these are the ideas ([[Samjna (concept)|saṃjñā]]) based on the appearances
* Samkalpa, Vikalpa (discrimination), the distinctions and connections between different names and ideas that allow us to distinguish between them
* Samyagjñāna (right knowledge), the knowledge gained by bodhisattvas who understand the true nature of things (i.e. Suchness) and who transcend the discriminations of worldly people
* [[Tathātā|Tathatā]] (Suchness), the truth, ultimate reality, which is beyond all words, images and discrimination, beyond all duality and plurality. 

The ''Lanka'' also closely connects this theory with the Yogacara theory of the [[Three natures|three inherent natures]]. According to the ''Lanka,'' image, naming and discrimination correspond to the parikalpita-svabhāva (the "fully conceptualized" nature) and the paratantra-svabhāva (dependent nature), while right knowledge and Suchness correspond to the pariniṣpanna-svabhāva (the fully accomplished nature).<ref name=":11" />

=== The buddha-nature and emptiness ===
A major topic found in the ''Laṅkāvatāra'' are the teachings on ''[[Buddha-nature|tathāgatagarbha]]'' (buddha-nature) also called ''buddhagotra'' (buddha disposition or buddha lineage) or ''tathagatagotra'', which is explained in many different ways throughout the sutra. The ''Lanka'' describes buddha-nature as "the purity of natural luminosity, it is primordially pure, endowed with the thirty-two major marks, and hidden within the bodies of all sentient beings...just like a gem of great value wrapped in a stained cloth, it is wrapped up in the cloth of the [[Skandha|skandhas]], dhātus, and [[Āyatana|āyatanas]], is tainted by the stains of desire, hatred, ignorance, and false imagination but is permanent, eternal, peaceful, and everlasting".<ref name=":0" /> 

Buddha-nature is also equated with the wisdom of [[Arya (Buddhism)|noble beings]], "the attainment of the realization of suchness" ([[Tathātā|tathata]]) and [[Three natures|the perfected nature (''pariniṣpanna'').]]<ref name=":0" /> Furthermore, the ''Lanka'' explains buddha-nature in a positive manner as the naturally [[luminous mind]] (''prabhāsvaracitta'') and also equates it with the "true self" which is realized by "those whose minds are not distracted by [[Śūnyatā|emptiness]]."<ref name=":0" />  

However, the ''Laṅkāvatāra'' also states that buddha-nature is not a self ([[Ātman (Buddhism)|atman]]), calls it selfless (nairātmya), and states that it is [[Śūnyatā|empty of self-nature]].<ref name=":10">Tokiwa, Gishin. "The Tathāgata-Garbha as the Fundamental Subject of the Four Satyas." ''Indogaku Bukkyogaku Kenkyu'' (Journal of Indian and Buddhist Studies) 33, no. 1 (1984): 13–18. https://www.jstage.jst.go.jp/article/ibk1952/33/1/33_1_403/_pdf/-char/en</ref><ref name=":0" /> The Lanka further states that buddha-nature is merely a skillful means ([[upaya]]) of teaching the dharma to non-buddhists (tīrthikas) who cling to a [[Ātman (Hinduism)|self]]:<blockquote> 

Mahāmati, my instruction on the ''tathāgatagarbha'' is not similar to the doctrine of the self of the tīrthikas. Rather, Mahāmati, the tathāgatas give the instruction on the ''tathāgatagarbha'' as bearing the meaning of words such as emptiness, true end, nirvāṇa, nonarising, signlessness, and wishlessness. Thus, for the sake of relinquishing what makes naive beings afraid of the lack of a self, the tathāgata arhats, the completely perfect buddhas, teach the sphere of nonconceptuality and nonappearance through the introductory instruction on the ''tathāgatagarbha''...Mahāmati, the tathāgatas teach the instruction on the ''tathāgatagarbha'' through teaching the ''tathāgatagarbha'' in order to attract the tīrthikas, who cling to the doctrine of the self. So how may those whose thinking falls into the views of conceiving an incorrect self and those who succumb to falling into the sphere of three [kinds of] liberation swiftly awaken to unsurpassable and completely perfect awakening? Mahāmati, it is for their sake that the tathāgata arhats, the completely perfect buddhas, give the instruction on the ''tathāgatagarbha''. Therefore, this is not similar to the doctrine of a self of the tīrthikas. Consequently, in order to put an end to the views of the tīrthikas, they need to become followers of the heart of nonself of a tathāgata (tathāgatanairātmyagarbha).<ref name=":0" />  </blockquote>According to Brunnholzl, the ''Lanka'' further states that what "all sūtras of all buddhas teach is nothing but emptiness, nonarising, nonduality, and the lack of nature".<ref name=":0"/> The sutra also states that "all characteristics of conceptions have terminated, either through the instruction on the ''tathāgatagarbha'' or through the instruction on identitylessness".<ref name=":0" /> Karl Brunnholzl notes that throughout various passages, the ''Lanka'' attempts to unify the positive buddha-nature teachings and the more negative emptiness teachings, presenting them as being equivalent to each other and as non-contradictory.<ref name=":0" />

=== The storehouse consciousness and buddha-nature ===
In other passages, the ''tathāgatagarbha'' ("buddha-womb" or buddha-source) is also equated with the "storehouse consciousness" (Skt. ''[[Eight Consciousnesses|ālayavijñāna]]''), the most fundamental layer of consciousness which contains the karmic seeds of [[Kleshas (Buddhism)|defilement]].<ref name=":0" /><ref name=":10" /> However, in other further passages, the ''tathāgatagarbha'' is also said to be free from all [[Eight Consciousnesses|eight consciousnesses]] and "free from the characteristics of mind, without consciousness and mentation."<ref name=":0" /> 

As noted by Brunnholzl, this paradoxical storehouse consciousness qua buddha-nature contains both contaminated and uncontaminated latent tendencies (''anusaya'').<ref name=":0" /> Further, it is both momentary and not momentary, it is the cause of virtue and non-virtue, it is the cause of all existences in saṃsāra, and thus it must be purified. But, at the same time, this same buddha-nature is described as indestructible, free from a self, naturally pure and free from the flaw of impermanence. It is compared to a dancer who does various performances and yet also to pure gold or a diamond that is never tarnished or changed.<ref name=":0" /> The Lanka sutra states that this buddha-nature storehouse-consciousness is something that cannot be fully understood by those who are not Buddhas.<ref name=":10" /> 

The ''Laṅkāvatāra'' explains this paradoxical buddha-nature consciousness which is defiled and yet undefiled as follows:<blockquote>Mahāmati, the ''tathāgatagarbha'' contains the causes of virtue and non-virtue and is the creator of all births and forms of existence. Free from a self and what is mine, like a dancer, it enters [all kinds of] dangerous forms of existence...Being impregnated by all kinds of beginningless latent tendencies of the impregnations of negative tendencies of discursiveness, it is called "ālaya-consciousness." Its body, together with the seven consciousnesses that arise from the ground of the latent tendencies of ignorance, always operates uninterruptedly, just like a great ocean and its waves, is free from the flaw of impermanence, is the cessation of the position of a self, and is utterly pure by nature. The seven consciousnesses such as mentation and the mental consciousness, which are other than this and arise and perish, are momentary, arise from the cause that is false imagination, focus on collections of shapes, activities, and distinct instances, cling to names and characteristics, do not understand that appearing forms and characteristics are one’s own mind, do not discriminate happiness and suffering, are not the cause for liberation, arise through and give rise to names, characteristics, and rising desire, and have the [ālaya-consciousness] as their cause and support...However, if the ālaya-consciousness, which is known as "the ''tathāgatagarbha''," does not undergo a change (parāvṛtti), there is no cessation of the seven active consciousnesses. For what reason? Because the consciousnesses flourish by virtue of [the ālaya-consciousness’s serving as] their cause and support, and [because the ālaya-consciousness] is not an object of any of the yogins [who are immersed] in the yogas of [[Śrāvaka|śrāvakas]], [[Pratyekabuddhayāna|pratyekabuddhas]], and tīrthikas. Even when one realizes one’s own lack of a personal self and apprehends the specific and general characteristics of the skandhas, dhātus, and āyatanas, this ''tathāgatagarbha'' still flourishes. It terminates only through seeing the five dharmas, the three natures, and phenomenal identitylessness....Therefore, Mahāmati, bodhisattva mahāsattvas who have this special goal should purify the tathāgata heart, which is known as "the ālaya-consciousness."<ref name=":0" />  </blockquote>Thus, the fundamental mind ([[Chitta (Buddhism)|citta]]) or storehouse consciousness is seen by the ''Lanka'' as neither separate from nor united with the defiled latent tendencies. Like a white piece of clothing that remains white underneath but can be dirtied by dust."<ref name=":0" />

=== The mistaken mind and the pure consciousness ===
[[File:Shadow of the peak when sun rising.jpg|thumb|350px|View of the sea from Mount Malaya showing the shadow of the mountain. The simile of the ocean and the waves is used in the sutra to illustrate the relationship between the pure consciousness and the defiled mind.]]
In some passages, the sutra also seems to divide the storehouse consciousness into two. In one passage these are called "the ultimate ālaya-consciousness and the ālaya of cognizance (vijñapti)," while in another passage, they are called "the true nature of the mind" (which is pure) and "the mind that arises from mistakenness."<ref name=":0" /> [[D. T. Suzuki|D.T. Suzuki]] similarly notes that according to the ''Laṅkā,'' the storehouse consciousness has two aspects "the Ālaya as it is in itself", called pāramālaya-vijñāna (the 'incessant' or prabandha aspect), and "the Ālaya as mental representation" (vijñaptir ālaya, the manifested or lakshaṇa aspect).<ref name=":17">Suzuki, D.T. (1999). ''The Laṅkāvatāra Sūtra: A Mahāyāna Text'', Introduction, p. xxv. Motilal Banarsidass Publ.</ref> Thus, it is the fluctuating (''pravṛitti'') aspect of the storehouse consciousness that gets caught up in the discrimination and craving of the manas consciousness, while the primitively pure (''prakṛitipuriśuddhi'') aspect of the storehouse does not.<ref name=":17" /> 

Indeed, this pure aspect of the storehouse consciousness is also called "something that has been in existence since the very first" (''pūrvadharmasthititā,'' or ''paurāṇasthitidharmatā'').<ref name=":18">Suzuki, D.T. (1999). ''The Laṅkāvatāra Sūtra: A Mahāyāna Text'', Introduction, p. xxix. Motilal Banarsidass Publ.</ref> According to Suzuki, the most common terms for this ultimate reality include: Tathatā ("suchness" or "thusness"), as well as "Satyatā, "the state of being true", Bhūtatā, "the state of being real", [[Dharmadhatu|Dharmadhātu]], "realm of truth", [[Nirvana (Buddhism)|Nirvana]], the Permanent (''nitya''), Sameness (''samatā''), the One (''advaya''), Cessation (''nirodha''), the Formless (''animitta''), Emptiness (''śūnyatā''), etc."<ref name=":18" />   

In yet another passage, the ''Lanka'' speaks of nine forms of consciousnesses (as opposed to the classic eight consciousnesses of Yogacara). This passage may have been the source of [[Paramartha|Paramārtha’s]] doctrine of the ninth consciousness, which he termed the *''amalavijñāna'' (pure consciousness).<ref name=":0" /> This distinction between an ultimate and a relative storehouse consciousness suggests that buddha-nature is not to be understood as completely equivalent with the storehouse consciousness, but rather is to be seen as the pure nature of the mind that remains once the mind has been purified of all adventitious stains (āgantukamala).<ref name=":0" /> 

=== Error, wisdom and awakening ===
According to the ''Laṅkāvatāra'' suffering and ignorance arises when consciousness engages in discrimination, representation and conceptualization. This error leads to the egoic consciousness, the ''manas'', which considers phenomena as being real and permanent and thus to craving and attachment. The key error of the mind is to consider any phenomena as being something other than mind.<ref name=":7">Ehman, Mark A. ''The Lankavatara Sutra'' in Charles S. Prebish (ed.) Buddhism: A Modern Perspective, Penn State Press, pp. 115-116, 2010.</ref> 

Meanwhile, liberation and awakening ([[Enlightenment in Buddhism|bodhi]]) arises when discrimination is brought to an end by a deep intuitive and non-conceptual knowledge ([[Jñāna|jñana]]) of suchness ([[Tathātā|tathata]]). Awakening is the result of the bringing to an end of various activities of consciousness, such as the discrimination of the egoic consciousness (manas) and the latent tendencies of the storehouse consciousness''.''<ref name=":7" /> As Gishin Tokiwa writes, awakening is attained when the discriminating storehouse consciousness "ceases to be the ground and object of the seven vijñanas (consciousnesses)" and when only the pure buddha-nature remains.<ref name=":10" /> 

This radical reversal of the activities of consciousness is called the turning around of the basis (''āśraya-parāvṛtti'')''.''<ref name=":7" /> To reach this radical transformation of the mind, the bodhisattva must purify his actions and thoughts (through Buddhist practices like ethical discipline and meditation) as well as develop insight into the nature of things (through hearing the teachings and meditating on emptiness)''.''<ref name=":7" /> 

The knowledge which knows the ultimate truth is a central topic of the Lanka and is variously termed pratyātmāryajñānagati (the state of noble knowledge realized by oneself), svapratyātma (inner self-realization), pratyātmagati (that which is realized by oneself), pratyātmagatigocara (the field realized by oneself) and pratyātma dharmatā (the Dharma nature realized by oneself) in the sutra.<ref name=":11">Akira Suganuma (1967), The ''Five Dharmas'' in the ''Lankavatarasutra''.</ref> Akira Suganuma writes that this "inner wisdom" is "that which all the teachings in the ''Laṅkāvatārasūtra'' indicate to us is to realize or accomplish."<ref name=":11" />  

According to [[D. T. Suzuki|D.T. Suzuki]], this transcendental wisdom (aryajñāna) of the Lanka is "an intuitive understanding which, penetrating through the surface of existence, sees into that which is the reason of everything logically and ontologically" as well as "a fundamental intuition into the truth of Mind-only and constitutes the Buddhist enlightenment."<ref name=":19">Suzuki, D.T. (1999). ''The Laṅkāvatāra Sūtra: A Mahāyāna Text'', Introduction, p. xxxii. Motilal Banarsidass Publ.</ref> Suzuki notes that aryajñāna is also designated by other terms, such as ''pravicayabuddhi'' ("an insight fixed upon the ultimate ground of existence"), ''svabuddhi'' (innate understanding), ''nirābhāsa'' or ''anābhāsa'' (imagelessness), ''nirvikalpa'' (beyond discrimination / concepts).<ref name=":19" /> The noble wisdom stands in contrast to ''vikalpabuddhi'', discriminative understanding, a relative and conceptual kind of knowledge based on duality and pluralities.<ref name=":19" />

=== Sudden and gradual purification ===
An important passage in the ''Laṅkāvatāra'' discusses how the purification of the mind occurs, and the passage states that it can occur gradually as well as suddenly.<ref>Watts, Alan (2011) ''The Way of Zen,'' p. 78. Knopf Doubleday Publishing Group.</ref><ref name=":8">Red Pine (2013). ''The Lankavatara Sutra: Translation and Commentary'', Chapter two (pp. 43-167), section XIV.</ref> In this passage, the ''Lanka'' states that the purification of the mind can happen "by degrees and not all at once. Like the [[gooseberry]], which ripens by degrees," and immediately after it also states that awakening can also happen "all at once":<ref name=":8" /> <blockquote>Or just as a clear mirror reflects formless images all at once, tathagatas likewise purify the stream of perceptions of beings’ minds by displaying pure, formless, undifferentiated realms all at once. Or just as the sun and moon illuminate images all at once, tathagatas likewise reveal the supreme realm of inconceivable wisdom all at once to those who have freed themselves of the habit-energy and misconceptions that are perceptions of their own minds. Or just as repository consciousness distinguishes such different perceptions of one’s mind as the realms of the body, its possessions, and the world around it all at once, [[Samboghakaya Buddha|nishyanda buddhas]] likewise bring beings to maturity in whatever realm they dwell all at once and lead practitioners to reside in Akanishtha Heaven.<ref name=":8" /> </blockquote>This idea was important for the establishment of the East Asian Buddhist doctrine of [[Subitism|sudden (dun 頓) enlightenment]], an important doctrine which was later widely debated and discussed in [[Zen|Zen Buddhism]].<ref>Jimmy Yu, ''Reimagining Chan Buddhism: Sheng Yen and the Creation of the Dharma Drum Lineage of Chan,'' p. 127'','' Routledge, 2021.</ref>

=== The Ultimate is beyond words ===
Another important idea found in the ''Laṅkāvatāra'' is how the ultimate reality (dharmata) transcends all language and conventional expressions and is free from verbal discrimination (''vāgvikalpa'').<ref name=":11" /> Because ultimate reality is eternal, free from arising and ceasing, and cannot be grasped or cognized (''[[anupalabdhi]]'') the sutra states that Buddhas "do not teach the doctrine that is dependent letters (''akṣarapatita'')."<ref name=":11" />

Because of this, all teachings in the sutra are not the ultimate, even though they point to the ultimate, like a finger pointing at the Moon. Thus, one should not become attached to the words of the sutra, to the letters (which are only provisional, ''[[Two truths doctrine|saṁvṛti]]'') and instead should focus on the ultimate meaning (''paramārtha'').<ref name=":11" /> The Lanka thus states:<blockquote>As the ignorant grasps the finger-tip (that points to the moon) and does not cognize the moon, so those who cling to the letter do not know my truth.<ref name=":11" /> </blockquote>The ''Laṅkāvatāra'' also states that even though Buddhas teach (in conventional fashion), they have never uttered even a single letter or syllable (''[[Aksara|akṣara]])'':<blockquote>the Tathagatas neither uttered nor answered even a letter (''ekam apy akṣaram''), because truths are beyond the letters. It does not mean, however, that (the Tathagatas) never declare what is connected with the benefit (artha) of beings. Depending upon discrimination, they declare anything. If, Mahamati, they do not depend upon discrimination, the scriptures containing all the truths will disappear, and when the scriptures disappear there will be no Buddhas, Sravakas, Pratyekabuddhas and Bodhisattvas; when they disappear, what is to be taught and to whom? For this reason, Mahamati, the Bodhisattva-Mahasattva should not cling to the words or letters in a canonical text...the Bodhisattva-Mahasattva should be in conformity with the meaning (''artha-pratiśaraṇa'') and not with the letter (''vyañjana'').<ref name=":11" /> </blockquote>According to Charles Willemen, this teaching of the ''Laṅkāvatāra'' is "the basis for Chan’s famous wordless teaching" which sees Chan as being taught "without words" (言说).<ref>Willemen, Charles. "Guṇabhadra to Bodhidharma: The Laṅkāvatāra-Sūtra and the Idea of Preaching without Words" in ''Journal of the Institute of Buddhist Studies,'' Third Series, Number 16, 2014.</ref>
