The Ānāpānasati Sutta (Pāli) or Ānāpānasmṛti Sūtra (Sanskrit), "Breath-Mindfulness Discourse," Majjhima Nikaya 118, is a discourse that details the Buddha's instruction on using awareness of the breath (anapana) as an initial focus for meditation.

The sutta includes sixteen steps of practice, and groups them into four tetrads, associating them with the four satipatthanas (placings of mindfulness). According to American scholar monk, Thanissaro Bhikkhu, this sutta contains the most detailed meditation instructions in the Pali Canon.Thanissaro Bhikkhu. The Steps of Breath Meditation.

Versions of the text

Theravāda Pāli Canon The Theravada Pali Canon version of the Ānāpānasati Sutta lists sixteen steps to compose the mind and body and cultivate insight. The Ānāpānasati Sutta is a celebrated text among Theravada Buddhists.For instance, in Southeast Asian countries, "Anapanasati Day" is the full-moon sabbath (uposatha) day in the eighth lunar month of Kattika (usually in November) (e.g., see Bullitt, 2005). In the Theravada Pāli Canon, this discourse is the 118th discourse in the Majjhima Nikāya (MN) and is thus frequently represented as "MN 118".A Romanized Pali version of this sutta can be found at http://www.metta.lk (SLTP, n.d.). Examples of English translations are Nanamoli (1998), Nanamoli & Bodhi (2001), Nhat Hanh (1988) and Thanissaro (2006a). In addition, in the Pali Text Society edition of the Pali Canon, this discourse is in the Majjhima Nikaya (M)'s third volume, starting on the 78th page and is thus sometimes referenced as "M iii 78".

Summary of the Pāli Canon version

Benefits The Buddha states that mindfulness of the breath, "developed and repeatedly practiced, is of great fruit, great benefit."Nanamoli (1998), p. 5, translation. See also Thanissaro (2006a) for similar wording. It fulfills the Four Foundations of Mindfulness (satipatthana).The Pali is: . SN 54.13 states: (underscore added). That is, the latter discourse identifies that it is the samādhi associated with anapanasati practice that leads to fulfillment of the four satipatthana. When these are developed and cultivated, they fulfill the Seven Factors of Enlightenment (bojjhanga). And when these are developed and cultivated, they fulfill "knowledge and freedom" (Bhikkhu Sujato), "true knowledge and deliverance" (Bhikkhu Bodhi), or "clear vision and deliverance" (Nanamoli).Nanamoli (1998), p. 5, translation. The Pali phrase being translated here as "clear vision and deliverance" is: . Vijja is the literal Pali antonym for avijja, traditionally translated as "ignorance" or "delusion" and canonically identified as the root of suffering (dukkha, cf. "Twelve Nidānas").

Establishing mindfulness To develop and cultivate mindfulness of breathing, a monk goes to the wilderness or forest, or to the root of a tree, or to an empty hut, sits down with crossed legs and the body erect, and establishes mindfulness in front or right there (parimukham), and mindfully breathes in and out.

Four tetrads The Ānāpānasati Sutta then describes the monitoring of the breath, and relates this to various experiences and practices. Following the classification of the four satipatthanas, these experiences and practices are grouped into a list of sixteen objects or steps of instructions, generally broken into four tetrads. These core sixteen steps appear in various Pali suttas collected in the Ānāpāna-saṃyutta. They also appear in various Chinese translations of the Agamas (such as in a parallel version of the Ananada sutta in the Samyukta-Āgama, SA 8.10) with minor differences as well as in the Vinayas of different schools. They are as follows:

First Tetrad: Contemplation of the Body (kāya) Breathing in long he knows (pajanati) 'I am breathing in long.' Breathing in short he knows 'I am breathing in short.' Breathing out long he knows 'I am breathing out long.'Breathing out short he knows 'I am breathing out short.' He trains himself 'breathing in, I experience the whole body' (sabbakāya).'breathing out, I experience the whole body.' He trains himself, 'breathing in, I calm the bodily formation.''breathing out, I calm the bodily formation.' (kāya-) Second Tetrad: Contemplation of the Feeling (vedanā) He trains himself, 'I will breathe in experiencing joy.'(pīti, also translated as "rapture")He trains himself, 'I will breathe out experiencing joy.' He trains himself, 'I will breathe in experiencing pleasure.' (sukha).He trains himself, 'I will breathe out experiencing pleasure.' He trains himself, 'I will breathe in experiencing mental formation.' (citta-)He trains himself, 'I will breathe out experiencing mental formation.' He trains himself, 'I will breathe in calming the mental formation.'He trains himself, 'I will breathe out calming the mental formation.' Third Tetrad: Contemplation of the Mind (citta) He trains himself, 'I will breathe in experiencing the mind.'He trains himself, 'I will breathe out experiencing the mind.' He trains himself, 'I will breathe in pleasing the mind.'He trains himself, 'I will breathe out pleasing the mind.' He trains himself, 'I will breathe in concentrating (samādhi) the mind.'He trains himself, 'I will breathe out concentrating the mind.' He trains himself, 'I will breathe in releasing the mind.'He trains himself, 'I will breathe out releasing the mind.' Fourth Tetrad: Contemplation of the Mental Objects (dhammā) He trains himself, 'I will breathe in observing (anupassi) impermanence.' (anicca)He trains himself, 'I will breath out observing impermanence.' He trains himself, 'I will breathe in observing dispassion.' (virāga)He trains himself, 'I will breath out observing dispassion. He trains himself, 'I will breathe in observing cessation.' (nirodha)He trains himself, 'I will breath out observing cessation.' He trains himself, 'I will breathe in observing relinquishment.' (paṭinissaggā)He trains himself, 'I will breath out observing relinquishment.'

Seven factors of awakening The sutra then explains how the four tetrads are correlated to the four satipatthanas. Next, the sutra explicates how contemplation of the four satipatthanas sets in the seven factors of awakening, which bring "clear knowing" and release.

In East Asian Buddhism The Ānāpānasmṛti Sūtra, as the text was known to Sanskritic early Buddhist schools in India, exists in several forms. There is a version of the Ānāpānasmṛti Sutra in the Ekottara Āgama preserved in the Chinese Buddhist canon. This version also teaches about the Four Dhyānas, recalling past lives, and the Divine Eye. The earliest translation of Ānāpānasmṛti instructions, however, was by An Shigao as a separate sutra (T602) in the 2nd century CE."The Relationships Between Traditional And Imported Thought And Culture In China: From The Standpoint of The Importation Of Buddhism" by Tang Yijie. Journal of Chinese Philosophy 15 (1988) pp.415-424 It is not part of the Sarvastivada Madhyama Āgama, but is instead an isolated text, although the sixteen steps are found elsewhere in the Madhyama and Samyukta Āgamas. The versions preserved in the Samyukta Agama are SA 815, SA 803, SA 810–812 and these three sutras have been translated into English by Thich Nhat HanhNhat Hanh, Awakening of the Heart: Essential Buddhist Sutras and Commentaries. and Bhikkhu Anālayo.

Metaphors

Hot-season rain cloud In a discourse variously entitled "At Vesali Discourse", in the Burmese edition of the Pali Canon (see http://www.tipitaka.org/romn/cscd/s0305m.mul9.xml). This edition is the basis for Bodhi (2000), pp. 1773-74. and "Foulness Discourse", in the Sinhala Sri Lanka Tripitaka Project (SLTP) edition of the Pali Canon (see http://www.metta.lk/tipitaka/2Sutta-Pitaka/3Samyutta-Nikaya/Samyutta5/53-Anapana-Samyutta/01-Ekadhammavaggo-p.html). The basis for this SLTP title is that it starts with the Buddha providing a talk about meditating on "foulness" (asubha, e.g., see Patikulamanasikara). (Traditionally, the intent of such a meditation is primarily to diminish one's attachment to their own or another's body.) (SN 54.9), the Buddha describes "concentration by mindfulness of breathing" (ānāpānassatisamādhi)In the Samyutta Nikaya (SN) chapter on breath-mindfulness, over half the discourses (SN 54.7 to 54.20) emphasize the concentration (samādhi) resulting from breath-mindfulness over breath-mindfulness per se. This is consistent with several enumeratons of Enlightenment factors (i.e., Five Faculties, Five Powers, Seven Factors of Enlightenment and Noble Eightfold Path) where the factor of mindfulness precedes that of concentration (Bodhi, 2000, pp. 1516-17). in the following manner: "Just as, bhikkhus, in the last month of the hot season, when a mass of dust and dirt has swirled up, a great rain cloud out of season disperses it and quells it on the spot, so too concentration by mindfulness of breathing, when developed and cultivated, is peaceful and sublime, an ambrosial pleasant dwelling, and it disperses and quells on the spot evil unwholesome states whenever they arise..."Bodhi (2000), p. 1774. After stating this, the Buddha states that such an "ambrosial pleasant dwelling" is achieved by pursuing the sixteen core instructions identified famously in the Anapanasati Sutta.

The skillful turner In the "Great Mindfulness Arousing Discourse" (Mahasatipatthana Sutta, DN 22) and the "Mindfulness Arousing Discourse" (Satipatthana Sutta, MN 10), the Buddha uses the following metaphor for elaborating upon the first two core instructions:
