This text, composed by Advayavajra and translated by Nyanchung, provides a technical justification for the term non-mental engagement (amānasikāra). The author seeks to correct common misunderstandings of the term by situating it within a specific scriptural and tantric framework. The argument proceeds by distinguishing the term from Sautrāntika interpretations and asserting its presence in the Hevajra Tantra and the Dhāraṇī of Entering Non-conceptuality. The text commits the reader to understanding non-mental engagement not as a mere absence of thought, but as a realization of the non-conceptual expanse and the inherent non-arising nature of all phenomena. This is further linked to the symbolic function of the syllable A, which represents the primordial lack of arising. Ultimately, the work functions as a concise instructional guide to clarify the concept of selflessness through the lens of non-engagement.
Provenance
About this text
A treatise providing a technical justification for the term non-mental engagement, the Amanasikāroddeśa (Tibetan: yid la mi byed pa ston pa) belongs to the tradition of the General Unexcelled Yoga Tantra Works. The work is attributed to the Indian authors Avadhūtipa Advayavajra and Maitrīpa. It was translated into the Tibetan language by Vajrapāṇi and bod kyi lo tsA ba gnyan chung, and is preserved in volume ཝི of the Tengyur. The author seeks to correct common misunderstandings of non-mental engagement (amānasikāra) by distinguishing the term from Sautrāntika interpretations and situating it within a specific scriptural framework. By referencing the Hevajra and the Dhāraṇī of Entering Non-conceptuality, the text argues that non-mental engagement is not a faulty expression or a mere absence of thought, but rather a realization of the non-conceptual expanse and the inherent nature of the mind. A scholar or serious reader consults this four-page work today to understand how the author utilizes tantric authority to clarify the concept of non-conceptuality and to resolve conceptual errors regarding the nature of mental engagement.
The work is significant for its attempt to reconcile sutra-based terminology with tantric practice, specifically within the Hevajra tradition. It demonstrates the scholarly effort to define precise technical terms to avoid philosophical misinterpretation in the transition from Indian to Tibetan contexts.

AnuvādaA Justification of [the Expression] “Mental Non-engagement”·
In the language of India: Amānasikārodara-nāma. In the language of Tibet: Yid la mi byed pa ston pa zhes bya ba (The Teaching on Non-Mental Engagement). Homage to the glorious Vajrasattva.
This so-called "non-mental engagement" (amānasikāra) is mostly misunderstood. Regarding this, some speak of it as a faulty expression, conceptualizing it as "not engaging with the attractive." To that, it should be said: the word la in skyes bu byas pa'i la is an elided locative case. By eliding the la and forming a compound, it becomes "non-mental engagement" (amānasikāra) and "the state of non-mental engagement" (amānasikāra). This formation is established by the rule "one who is firm on the battlefield" (raṇasthira). Therefore, this is not a faulty expression.
Furthermore, some claim this term is established by its own definition but is not a Buddhist term. That is not so, because it is seen in many sūtras. From the Āryasarvabuddhaviṣayāvatārajñānālokālaṃkāra-nāma-mahāyānasūtra: "Phenomena that are non-mental engagements are virtuous; phenomena that are mental engagements are non-virtuous." Likewise:
"Not analyzed by conceptualization,
The mind that is utterly non-abiding,
Without mindfulness and without mental engagement—
I prostrate and bow to that which is without focal point."
Similarly, from the Nirvikalpapraveśadhāraṇī: "The sign of conceptualization for a bodhisattva mahāsattva is the conceptualization of appearances; it is the complete abandonment of non-mental engagement."
Because there are many scriptural passages in various other sūtras, I have not written them here. Now, as for the other statement, this phrase belongs to the Sautrāntikas and is not a mantra. If one asks why, it is because it is seen in the sūtras. That is not so, for it is said in the Hevajra: "By its very nature, there is no mind, and there are no mental factors." Likewise: "Therefore, if one does not meditate with the mind, one should meditate on all beings." By the meaning of this, one should understand it as "non-mental engagement." Furthermore, it is said: "It also exists in the tantras, because a non-affirming negation is an object of non-existence." It should be expressed as the non-existence of a thing. That is not so; the negation of an existing thing is a non-affirming negation. Alternatively, the negation of a consequence that is not a consequence is a non-affirming negation. The meaning of this is like the example: "The king’s queen does not see the sun." This does not mean that the king’s wife is not a human; rather, because she is so well-concealed, even the sun does not see her. Here, the negation does not make the sun non-existent. What is it then? It negates the possibility of anyone seeing the sun, such as the king’s wives. Similarly, regarding non-mental engagement, it negates whatever mental engagement exists, such as subject and object, but it does not negate the state of non-mental engagement itself; thus, there is no fault here. When this is explained as: "Non-mental engagement is the characteristic of permanence and nihilism," then it is said: "If one does not mentally engage with permanence, nihilism, and so forth, [that is non-mental engagement]."
These [terms] harm all attachment by means of the expression "non-mental engagement" (amanasikāra). Thus, the Blessed One stated in the Dhāraṇī of Entering Non-conceptuality: "Noble son, for what reason is the non-conceptual expanse called 'mental engagement'? It is because, having completely transcended the signs of all conceptualization, it is to be taken up." By these [words], the complete transcendence of all conceptualization is shown by means of the term "mental engagement."
The position of "non-imagined" (avikalpita) is also faultless. For example, when one says, "Bring a non-Brahmin," it is clear that one is referring to a king or similar person who resembles a Brahmin, and not someone of a different class, such as a chariot-maker. In this context as well, one abides in the awareness that lacks intrinsic nature; by means of these, one abides in the non-dual discourse of the illusion-like. From what, then, would the consequence of a nihilistic view follow? However, it is a mere convention of non-existence; this word is to be expressed as a duality. It is not that existence is negated because of the absence of an illusion or a truly established entity, nor is it non-existence. By this reasoning, the meaning of negating the world would be undermined; here, it is merely a verbal expression.
"Mental engagement" (manasikāra) in which the letter i is primary is "non-mental engagement" (amanasikāra); this is a compound formed by eliding the middle term, like the "King of Leaves" (palāśarāja). Whatever is mental engagement, all of that is a, the meaning of non-arising. If one asks what the Blessed One taught: [he taught that] all mental engagement is a, the meaning of non-arising. What did the Blessed One teach?
Regarding the phrase "non-arising," this refers to the syllable A. As it is stated in the Mantra Chapter of the Hevajra Tantra: ākāro mukhaṃ sarvadharmāṇām ādyanutpannatvāt and so forth. The meaning of this is that because all phenomena are from the very beginning without arising, the syllable A is the primary gateway; thus, A is applied as the characteristic of non-arising.
Likewise, the Chanting of the Names (Nāmasaṃgīti) states:
"The syllable A is the supreme of all letters,
The sacred letter of great significance.
Arising from within, it is without birth,
Transcending all verbal expression."
Alternatively, in this context, A is the seed-syllable of selflessness. As it is said in the Hevajra Tantra: "The first of the vowels is Nairātmyā (Selfless Lady)." Through these, all mental engagements are described as being without intrinsic nature because they are selfless.
"The first vowel is the nature;
What is called 'intellect' is designated as insight.
That itself is the Blessed One, Insight,
The very application of the completion stage."
Alternatively, A is a term for luminosity, and "mental engagement" is a term for self-consecration. Thus, it is "non-mental-engagement" (amanasikāra) because it is both A and mental engagement. By this, one generates the authentic awareness of the non-dual continuum—the union of emptiness and compassion, the inconceivable state of non-mental-engagement, the nature of self-consecration, and luminosity.
The Instruction on Non-mental Engagement: Clarifying Selflessness, composed by the great master Advayavajra, is complete. It was edited by the Indian abbot Vajrapāṇi and the Tibetan translator Nyanchung.
