"Yes, Ananda, there is one quality that, when developed & pursued, brings four qualities to completion; and four qualities that, when developed & pursued, bring seven qualities to completion; and seven qualities that, when developed & pursued, bring two qualities to completion. And what is the one quality that, when developed & pursued, brings four qualities to completion? What are the four qualities that, when developed & pursued, bring seven qualities to completion? What are the seven qualities that, when developed & pursued, bring two qualities to completion?
"Mindfulness of in-&-out breathing, when developed & pursued, brings the four frames of reference (foundations of mindfulness) to completion. The four frames of reference, when developed & pursued, bring the seven factors for Awakening to completion. The seven factors for Awakening, when developed & pursued, bring clear knowing & release to completion.
"Now how is mindfulness of in-&-out breathing developed & pursued so as to bring the four frames of reference to their culmination?
"There is the case where a monk, having gone to the wilderness, to the shade of a tree, or to an empty building, sits down folding his legs crosswise, holding his body erect, and setting mindfulness to the fore. Always mindful, he breathes in; mindful he breathes out.
"[1] Breathing in long, he discerns that he is breathing in long; or breathing out long, he discerns that he is breathing out long. [2] Or breathing in short, he discerns that he is breathing in short; or breathing out short, he discerns that he is breathing out short. [3] He trains himself to breathe in sensitive to the entire body, and to breathe out sensitive to the entire body. [4] He trains himself to breathe in calming the bodily processes, and to breathe out calming the bodily processes.
"[5] He trains himself to breathe in sensitive to rapture, and to breathe out sensitive to rapture. [6] He trains himself to breathe in sensitive to pleasure, and to breathe out sensitive to pleasure. [7] He trains himself to breathe in sensitive to mental processes, and to breathe out sensitive to mental processes. [8] He trains himself to breathe in calming mental processes, and to breathe out calming mental processes.
"[9] He trains himself to breathe in sensitive to the mind, and to breathe out sensitive to the mind. [10] He trains himself to breathe in satisfying the mind, and to breathe out satisfying the mind. [11] He trains himself to breathe in steadying the mind, and to breathe out steadying the mind. [12] He trains himself to breathe in releasing the mind, and to breathe out releasing the mind.
"[13] He trains himself to breathe in focusing on inconstancy, and to breathe out focusing on inconstancy. [14] He trains himself to breathe in focusing on dispassion [literally, fading], and to breathe out focusing on dispassion. [15] He trains himself to breathe in focusing on cessation, and to breathe out focusing on cessation. [16] He trains himself to breathe in focusing on relinquishment, and to breathe out focusing on relinquishment.
"[1] Now, on whatever occasion a monk breathing in long discerns that he is breathing in long; or breathing out long, discerns that he is breathing out long; or breathing in short, discerns that he is breathing in short; or breathing out short, discerns that he is breathing out short; trains himself to breathe in... &... out sensitive to the entire body; trains himself to breathe in... &... out calming the bodily processes: On that occasion the monk remains focused on the body in & of itself -- ardent, alert, & mindful -- subduing greed & distress with reference to the world. I tell you that this -- the in-&-out breath -- is classed as a body among bodies, which is why the monk on that occasion remains focused on the body in & of itself -- ardent, alert, & mindful -- putting aside greed & distress with reference to the world.
"[2] On whatever occasion a monk trains himself to breathe in... &... out sensitive to rapture; trains himself to breathe in... &... out sensitive to pleasure; trains himself to breathe in... &... out sensitive to mental processes; trains himself to breathe in... &... out calming mental processes: On that occasion the monk remains focused on feelings in & of themselves -- ardent, alert, & mindful -- subduing greed & distress with reference to the world. I tell you that this -- close attention to in-&-out breaths -- is classed as a feeling among feelings, which is why the monk on that occasion remains focused on feelings in & of themselves -- ardent, alert, & mindful -- putting aside greed & distress with reference to the world.
"[3] On whatever occasion a monk trains himself to breathe in... &... out sensitive to the mind; trains himself to breathe in... &... out satisfying the mind; trains himself to breathe in... &... out steadying the mind; trains himself to breathe in... &... out releasing the mind: On that occasion the monk remains focused on the mind in & of itself -- ardent, alert, & mindful -- subduing greed & distress with reference to the world. I don't say that there is mindfulness of in-&-out breathing in one of confused mindfulness and no alertness, which is why the monk on that occasion remains focused on the mind in & of itself -- ardent, alert, & mindful -- putting aside greed & distress with reference to the world.
"[4] On whatever occasion a monk trains himself to breathe in... &... out focusing on inconstancy; trains himself to breathe in... &... out focusing on dispassion; trains himself to breathe in... &... out focusing on cessation; trains himself to breathe in... &... out focusing on relinquishment: On that occasion the monk remains focused on mental qualities in & of themselves -- ardent, alert, & mindful -- subduing greed & distress with reference to the world. He who sees clearly with discernment the abandoning of greed & distress is one who oversees with equanimity, which is why the monk on that occasion remains focused on mental qualities in & of themselves -- ardent, alert, & mindful -- putting aside greed & distress with reference to the world.
"This is how mindfulness of in-&-out breathing is developed & pursued so as to bring the four frames of reference to their culmination.
"And how are the four frames of reference developed & pursued so as to bring the seven factors for Awakening to their culmination?
"[1] On whatever occasion the monk remains focused on the body in & of itself -- ardent, alert, & mindful -- putting aside greed & distress with reference to the world, on that occasion his mindfulness is steady & without lapse. When his mindfulness is steady & without lapse, then mindfulness as a factor for Awakening becomes aroused. He develops it, and for him it goes to the culmination of its development.
"[2] Remaining mindful in this way, he examines, analyzes, & comes to a comprehension of that quality with discernment. When he remains mindful in this way, examining, analyzing, & coming to a comprehension of that quality with discernment, then analysis of qualities as a factor for Awakening becomes aroused. He develops it, and for him it goes to the culmination of its development.
"[3] In one who examines, analyzes, & comes to a comprehension of that quality with discernment, unflagging persistence is aroused. When unflagging persistence is aroused in one who examines, analyzes, & comes to a comprehension of that quality with discernment, then persistence as a factor for Awakening becomes aroused. He develops it, and for him it goes to the culmination of its development.
"[4] In one whose persistence is aroused, a rapture not-of-the-flesh arises. When a rapture not-of-the-flesh arises in one whose persistence is aroused, then rapture as a factor for Awakening becomes aroused. He develops it, and for him it goes to the culmination of its development.
"[5] For one who is enraptured, the body grows calm and the mind grows calm. When the body & mind of an enraptured monk grow calm, then serenity as a factor for Awakening becomes aroused. He develops it, and for him it goes to the culmination of its development.
"[6] For one who is at ease -- his body calmed -- the mind becomes concentrated. When the mind of one who is at ease -- his body calmed -- becomes concentrated, then concentration as a factor for Awakening becomes aroused. He develops it, and for him it goes to the culmination of its development.
"[7] He oversees the mind thus concentrated with equanimity. When he oversees the mind thus concentrated with equanimity, equanimity as a factor for Awakening becomes aroused. He develops it, and for him it goes to the culmination of its development.
[Similarly with the other three frames of reference: feelings, mind, & mental qualities.]
"This is how the four frames of reference are developed & pursued so as to bring the seven factors for Awakening to their culmination.
"And how are the seven factors for Awakening developed & pursued so as to bring clear knowing & release to their culmination? There is the case where a monk develops mindfulness as a factor for Awakening dependent on seclusion... dispassion... cessation, resulting in relinquishment. He develops analysis of qualities as a factor for Awakening... persistence as a factor for Awakening... rapture as a factor for Awakening... serenity as a factor for Awakening... concentration as a factor for Awakening... equanimity as a factor for Awakening dependent on seclusion... dispassion... cessation, resulting in relinquishment.
"This is how the seven factors for Awakening, when developed & pursued, bring clear knowing & release to their culmination."
That is what the Blessed One said. Gratified, Ven. Ananda delighted in the Blessed One's words.
