II. MINDFULNESS IMMERSED IN THE BODY
Kāyagatā-sati Sutta (Majjhima Nikāya 119)
I have heard that on one occasion the Blessed One was staying in Sāvatthi at Jeta’s Grove, Anāthapiṇḍika’s monastery. Now at that time a large number of monks, after the meal, on returning from their alms round, had gathered at the meeting hall when this discussion arose: “Isn’t it amazing, friends! Isn’t it astounding!—the extent to which mindfulness immersed in the body, when developed & pursued, is said by the Blessed One who knows, who sees—the worthy one, rightly self-awakened—to be of great fruit & great benefit.” And this discussion came to no conclusion.
Then the Blessed One, emerging from his seclusion in the late afternoon, went to the meeting hall and, on arrival, sat down on a seat made ready. As he was sitting there, he addressed the monks: “For what topic are you gathered together here? And what was the discussion that came to no conclusion?”
“Just now, lord, after the meal, on returning from our alms round, we gathered at the meeting hall when this discussion arose: ‘Isn’t it amazing, friends! Isn’t it astounding!—the extent to which mindfulness immersed in the body, when developed & pursued, is said by the Blessed One who knows, who sees—the worthy one, rightly self-awakened—to be of great fruit & great benefit.’ This was the discussion that had come to no conclusion when the Blessed One arrived.”
[The Blessed One said:] “And how, monks, is mindfulness immersed in the body developed, how is it pursued, so as to be of great fruit & great benefit?
“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.
“Breathing in long, he discerns, ‘I am breathing in long’; or breathing out long, he discerns, ‘I am breathing out long.’ Or breathing in short, he discerns, ‘I am breathing in short’; or breathing out short, he discerns, ‘I am breathing out short.’ He trains himself, ‘I will breathe in sensitive to the entire body.’ He trains himself, ‘I will breathe out sensitive to the entire body.’ He trains himself, ‘I will breathe in calming bodily fabrication [the in-&-out breath].’ He trains himself, ‘I will breathe out calming bodily fabrication.’ And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Furthermore, when walking, the monk discerns, ‘I am walking.’ When standing, he discerns, ‘I am standing.’ When sitting, he discerns, ‘I am sitting.’ When lying down, he discerns, ‘I am lying down.’ Or however his body is disposed, that is how he discerns it. And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Furthermore, when going forward & returning, he makes himself fully alert; when looking toward & looking away… when bending & extending his limbs… when carrying his outer cloak, his upper robe & his bowl… when eating, drinking, chewing, & savoring… when urinating & defecating… when walking, standing, sitting, falling asleep, waking up, talking, & remaining silent, he makes himself fully alert. And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Furthermore, the monk reflects on this very body from the soles of the feet on up, from the crown of the head on down, surrounded by skin and full of various kinds of unclean things: ‘In this body there are head hairs, body hairs, nails, teeth, skin, flesh, tendons, bones, bone marrow, kidneys, heart, liver, pleura, spleen, lungs, large intestines, small intestines, gorge, feces, bile, phlegm, pus, blood, sweat, fat, tears, skin-oil, saliva, mucus, fluid in the joints, urine.’ Just as if a sack with openings at both ends were full of various kinds of grain—wheat, rice, mung beans, kidney beans, sesame seeds, husked rice—and a man with good eyesight, pouring it out, were to reflect, ‘This is wheat. This is rice. These are mung beans. These are kidney beans. These are sesame seeds. This is husked rice’; in the same way, the monk reflects on this very body from the soles of the feet on up, from the crown of the head on down, surrounded by skin and full of various kinds of unclean things: ‘In this body there are head hairs, body hairs, nails, teeth, skin, flesh, tendons, bones, bone marrow, kidneys, heart, liver, pleura, spleen, lungs, large intestines, small intestines, gorge, feces, bile, phlegm, pus, blood, sweat, fat, tears, skin-oil, saliva, mucus, fluid in the joints, urine.’ And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Furthermore, the monk contemplates this very body—however it stands, however it is disposed—in terms of properties: ‘In this body there is the earth property, the liquid property, the fire property, & the wind property.’ Just as an adept butcher or butcher’s apprentice, having killed a cow, would sit at a crossroads cutting it up into pieces, the monk contemplates this very body—however it stands, however it is disposed—in terms of properties: ‘In this body there is the earth property, the liquid property, the fire property, & the wind property.’ And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Furthermore, as if he were to see a corpse cast away in a charnel ground—one day, two days, three days dead—bloated, livid, & festering, he applies it to this very body, ‘This body, too: Such is its nature, such is its future, such its unavoidable fate’…
“Or again, as if he were to see a corpse cast away in a charnel ground, picked at by crows, vultures, & hawks, by dogs, hyenas, & various other creatures…a skeleton smeared with flesh & blood, connected with tendons…a fleshless skeleton smeared with blood, connected with tendons…a skeleton without flesh or blood, connected with tendons…bones detached from their tendons, scattered in all directions—here a hand bone, there a foot bone, here a shin bone, there a thigh bone, here a hip bone, there a back bone, here a rib, there a chest bone, here a shoulder bone, there a neck bone, here a jaw bone, there a tooth, here a skull…the bones whitened, somewhat like the color of shells…piled up, more than a year old…decomposed into a powder: He applies it to this very body, ‘This body, too: Such is its nature, such is its future, such its unavoidable fate.’
“And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
The Four Jhānas
“Furthermore, quite secluded from sensuality, secluded from unskillful qualities, he enters & remains in the first jhāna: rapture & pleasure born of seclusion, accompanied by directed thought & evaluation. He permeates & pervades, suffuses & fills this very body with the rapture & pleasure born of seclusion. Just as if an adept bathman or bathman’s apprentice would pour bath powder into a brass basin and knead it together, sprinkling it again & again with water, so that his ball of bath powder—saturated, moisture-laden, permeated within & without—would nevertheless not drip; even so, the monk permeates … this very body with the rapture & pleasure born of seclusion. There is nothing of his entire body unpervaded by rapture & pleasure born of seclusion. And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Then, with the stilling of directed thoughts & evaluations, he enters & remains in the second jhāna: rapture & pleasure born of concentration, unification of awareness free from directed thought & evaluation—internal assurance. He permeates & pervades, suffuses & fills this very body with the rapture & pleasure born of concentration. Just like a lake with spring-water welling up from within, having no inflow from the east, west, north, or south, and with the skies supplying abundant showers time & again, so that the cool fount of water welling up from within the lake would permeate & pervade, suffuse & fill it with cool waters, there being no part of the lake unpervaded by the cool waters; even so, the monk permeates … this very body with the rapture & pleasure born of concentration. There is nothing of his entire body unpervaded by rapture & pleasure born of concentration. And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Then, with the fading of rapture, he remains equanimous, mindful, & alert, and senses pleasure with the body. He enters & remains in the third jhāna, of which the noble ones declare, ‘Equanimous & mindful, he has a pleasant abiding.’ He permeates & pervades, suffuses & fills this very body with the pleasure divested of rapture. Just as in a lotus pond, some of the lotuses, born & growing in the water, stay immersed in the water and flourish without standing up out of the water, so that they are permeated & pervaded, suffused & filled with cool water from their roots to their tips, and nothing of those lotuses would be unpervaded with cool water; even so, the monk permeates … this very body with the pleasure divested of rapture. There is nothing of his entire body unpervaded with pleasure divested of rapture. And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
“Then, with the abandoning of pleasure & pain—as with the earlier disappearance of elation & distress—he enters & remains in the fourth jhāna: purity of equanimity & mindfulness, neither-pleasure-nor-pain. He sits, permeating the body with a pure, bright awareness. Just as if a man were sitting covered from head to foot with a white cloth so that there would be no part of his body to which the white cloth did not extend; even so, the monk sits, permeating the body with a pure, bright awareness. There is nothing of his entire body unpervaded by pure, bright awareness. And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.
Fullness of Mind
“Monks, whoever develops & pursues mindfulness immersed in the body encompasses whatever skillful qualities are on the side of clear knowing. Just as whoever pervades the great ocean with his awareness encompasses whatever rivulets flow down into the ocean, in the same way, whoever develops & pursues mindfulness immersed in the body encompasses whatever skillful qualities are on the side of clear knowing.
“In whomever mindfulness immersed in the body is not developed, not pursued, Māra gains entry, Māra gains a foothold.
“Suppose that a man were to throw a heavy stone ball into a pile of wet clay. What do you think, monks—would the heavy stone ball gain entry into the pile of wet clay?”
“Yes, lord.”
“In the same way, in whomever mindfulness immersed in the body is not developed, not pursued, Māra gains entry, Māra gains a foothold.
“Now, suppose that there were a dry, sapless piece of timber, and a man were to come along with an upper fire-stick, thinking, ‘I’ll light a fire. I’ll produce heat.’ What do you think—would he be able to light a fire and produce heat by rubbing the upper fire-stick in the dry, sapless piece of timber?”
“Yes, lord.”
“In the same way, in whomever mindfulness immersed in the body is not developed, not pursued, Māra gains entry, Māra gains a foothold.
“Now, suppose that there were an empty, hollow water-pot set on a stand, and a man were to come along carrying a load of water. What do you think—would he get a place to put his water?”
“Yes, lord.”
“In the same way, in whomever mindfulness immersed in the body is not developed, not pursued, Māra gains entry, Māra gains a foothold.
“Now, in whomever mindfulness immersed in the body is developed, is pursued, Māra gains no entry, Māra gains no foothold. Suppose that a man were to throw a ball of string against a door panel made entirely of heartwood. What do you think—would that light ball of string gain entry into that door panel made entirely of heartwood?”
“No, lord.”
“In the same way, in whomever mindfulness immersed in the body is developed, is pursued, Māra gains no entry, Māra gains no foothold.
“Now, suppose that there were a wet, sappy piece of timber, and a man were to come along with an upper fire-stick, thinking, ‘I’ll light a fire. I’ll produce heat.’ What do you think—would he be able to light a fire and produce heat by rubbing the upper fire-stick in the wet, sappy piece of timber?”
“No, lord.”
“In the same way, in whomever mindfulness immersed in the body is developed, is pursued, Māra gains no entry, Māra gains no foothold.
“Now, suppose that there were a water-pot set on a stand, full of water up to the brim so that crows could drink out of it, and a man were to come along carrying a load of water. What do you think—would he get a place to put his water?”
“No, lord.”
“In the same way, in whomever mindfulness immersed in the body is developed, is pursued, Māra gains no entry, Māra gains no foothold.
An Opening to the Higher Knowledges
“When anyone has developed & pursued mindfulness immersed in the body, then whichever of the six higher knowledges he turns his mind to know & realize, he can witness them for himself whenever there is an opening.
“Suppose that there were a water jar, set on a stand, brimful of water so that a crow could drink from it. If a strong man were to tip it in any way at all, would water spill out?”
“Yes, lord.”
“In the same way, when anyone has developed & pursued mindfulness immersed in the body, then whichever of the six higher knowledges he turns his mind to know & realize, he can witness them for himself whenever there is an opening.
“Suppose there were a rectangular water tank—set on level ground, bounded by dikes—brimful of water so that a crow could drink from it. If a strong man were to loosen the dikes anywhere at all, would water spill out?”
“Yes, lord.”
“In the same way, when anyone has developed & pursued mindfulness immersed in the body, then whichever of the six higher knowledges he turns his mind to know & realize, he can witness them for himself whenever there is an opening.
“Suppose there were a chariot on level ground at four crossroads, harnessed to thoroughbreds, waiting with whips lying ready, so that an adept driver, a trainer of tamable horses, might mount and—taking the reins with his left hand and the whip with his right—drive out & back, to whatever place & by whichever road he liked; in the same way, when anyone has developed & pursued mindfulness immersed in the body, then whichever of the six higher knowledges he turns his mind to know & realize, he can witness them for himself whenever there is an opening.
Ten Benefits
“Monks, for one in whom mindfulness immersed in the body is cultivated, developed, pursued, given a means of transport, given a grounding, steadied, consolidated, & well-undertaken, ten benefits can be expected. Which ten?
“(1) He conquers displeasure & delight, and displeasure does not conquer him. He remains victorious over any displeasure that has arisen.
“(2) He conquers fear & dread, and fear & dread to not conquer him. He remains victorious over any fear & dread that have arisen.
“(3) He is resistant to cold, heat, hunger, thirst, the touch of gadflies & mosquitoes, wind & sun & creeping things; to abusive, hurtful language; he is the sort that can endure bodily feelings that, when they arise, are painful, sharp, stabbing, fierce, distasteful, disagreeable, deadly.
“(4) He can attain at will, without trouble or difficulty, the four jhānas—heightened mental states providing a pleasant abiding in the here & now.
“(5) He wields manifold supranormal powers. Having been one he becomes many; having been many he becomes one. He appears. He vanishes. He goes unimpeded through walls, ramparts, & mountains as if through space. He dives in & out of the earth as if it were water. He walks on water without sinking as if it were dry land. Sitting cross-legged he flies through the air like a winged bird. With his hand he touches & strokes even the sun & moon, so mighty & powerful. He exercises influence with his body even as far as the Brahmā worlds.
“(6) He hears—by means of the divine ear-element, purified & surpassing the human—both kinds of sounds: divine & human, whether near or far.
“(7) He knows the awareness of other beings, other individuals, having encompassed it with his own awareness. He discerns a mind with passion as a mind with passion, and a mind without passion as a mind without passion. He discerns a mind with aversion as a mind with aversion, and a mind without aversion as a mind without aversion. He discerns a mind with delusion as a mind with delusion, and a mind without delusion as a mind without delusion. He discerns a restricted mind as a restricted mind, and a scattered mind as a scattered mind. He discerns an enlarged mind as an enlarged mind, and an unenlarged mind as an unenlarged mind. He discerns an excelled mind [one that is not at the most excellent level] as an excelled mind, and an unexcelled mind as an unexcelled mind. He discerns a concentrated mind as a concentrated mind, and an unconcentrated mind as an unconcentrated mind. He discerns a released mind as a released mind, and an unreleased mind as an unreleased mind.
“(8) He recollects his manifold past lives, i.e., one birth, two births, three births, four, five, ten, twenty, thirty, forty, fifty, one hundred, one thousand, one hundred thousand, many eons of cosmic contraction, many eons of cosmic expansion, many eons of cosmic contraction & expansion, [recollecting], ‘There I had such a name, belonged to such a clan, had such an appearance. Such was my food, such my experience of pleasure & pain, such the end of my life. Passing away from that state, I re-arose there. There too I had such a name, belonged to such a clan, had such an appearance. Such was my food, such my experience of pleasure & pain, such the end of my life. Passing away from that state, I re-arose here.’ Thus he remembers his manifold past lives in their modes & details.
“(9) He sees—by means of the divine eye, purified & surpassing the human—beings passing away & re-appearing, and he discerns how they are inferior & superior, beautiful & ugly, fortunate & unfortunate in accordance with their kamma: ‘These beings—who were endowed with bad conduct of body, speech, & mind, who reviled the noble ones, held wrong views and undertook actions under the influence of wrong views—with the break-up of the body, after death, have re-appeared in the plane of deprivation, the bad destination, the lower realms, in hell. But these beings—who were endowed with good conduct of body, speech, & mind, who did not revile the noble ones, who held right views and undertook actions under the influence of right views—with the break-up of the body, after death, have re-appeared in the good destinations, in the heavenly world.’ Thus—by means of the divine eye, purified & surpassing the human—he sees beings passing away & re-appearing, and he discerns how they are inferior & superior, beautiful & ugly, fortunate & unfortunate in accordance with their kamma.
“(10) Through the ending of the mental effluents, he remains in the effluent-free release of awareness & release of discernment, having known and made them manifest for himself right in the here & now.
“Monks, for one in whom mindfulness immersed in the body is cultivated, developed, pursued, given a means of transport, given a grounding, steadied, consolidated, & well-undertaken, these ten benefits can be expected.”
That is what the Blessed One said. Gratified, the monks delighted in the Blessed One’s words.
Mindfulness of In-&-Out Breathing
“Now how is mindfulness of in-&-out breathing developed & pursued so as to be of great fruit, of great benefit?
“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.1 Always mindful, he breathes in; mindful he breathes out.
“(1) Breathing in long, he discerns, ‘I am breathing in long’; or breathing out long, he discerns, ‘I am breathing out long.’ (2) Or breathing in short, he discerns, ‘I am breathing in short’; or breathing out short, he discerns, ‘I am breathing out short.’ (3) He trains himself, ‘I will breathe in sensitive to the entire body.’2 He trains himself, ‘I will breathe out sensitive to the entire body.’ (4) He trains himself, ‘I will breathe in calming bodily fabrication.’3 He trains himself, ‘I will breathe out calming bodily fabrication.’
“(5) He trains himself, ‘I will breathe in sensitive to rapture.’ He trains himself, ‘I will breathe out sensitive to rapture.’ (6) He trains himself, ‘I will breathe in sensitive to pleasure.’ He trains himself, ‘I will breathe out sensitive to pleasure.’ (7) He trains himself, ‘I will breathe in sensitive to mental fabrication.’4 He trains himself, ‘I will breathe out sensitive to mental fabrication.’ (8) He trains himself, ‘I will breathe in calming mental fabrication.’ He trains himself, ‘I will breathe out calming mental fabrication.’
“(9) He trains himself, ‘I will breathe in sensitive to the mind.’ He trains himself, ‘I will breathe out sensitive to the mind.’ (10) He trains himself, ‘I will breathe in satisfying the mind.’ He trains himself, ‘I will breathe out satisfying the mind.’ (11) He trains himself, ‘I will breathe in steadying the mind.’ He trains himself, ‘I will breathe out steadying the mind. (12) He trains himself, ‘I will breathe in releasing the mind.’ He trains himself, ‘I will breathe out releasing the mind.’5
“(13) He trains himself, ‘I will breathe in focusing on inconstancy.’ He trains himself, ‘I will breathe out focusing on inconstancy.’ (14) He trains himself, ‘I will breathe in focusing on dispassion [literally, fading].’ He trains himself, ‘I will breathe out focusing on dispassion.’ (15) He trains himself, ‘I will breathe in focusing on cessation.’ He trains himself, ‘I will breathe out focusing on cessation.’ (16) He trains himself, ‘I will breathe in focusing on relinquishment.’ He trains himself, ‘I will breathe out focusing on relinquishment.’
“This is how mindfulness of in-&-out breathing is developed & pursued so as to be of great fruit, of great benefit.
The Four Establishings of Mindfulness
“And how is mindfulness of in-&-out breathing developed & pursued so as to bring the four establishings of mindfulness to their culmination?
“(1) On whatever occasion a monk breathing in long discerns, ‘I am breathing in long’; or breathing out long, discerns, ‘I am breathing out long’; or breathing in short, discerns, ‘I am breathing in short’; or breathing out short, discerns, ‘I am breathing out short’; trains himself, ‘I will breathe in…&…out sensitive to the entire body’; trains himself, ‘I will breathe in…&…out calming bodily fabrication’: On that occasion the monk remains focused on the body in & of itself—ardent, alert, & mindful—putting aside greed & distress with reference to the world. I tell you, monks, 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, ‘I will breathe in…&…out sensitive to rapture’; trains himself, ‘I will breathe in…&…out sensitive to pleasure’; trains himself, ‘I will breathe in…&…out sensitive to mental fabrication’; trains himself, ‘I will breathe in…&…out calming mental fabrication’: On that occasion the monk remains focused on feelings in & of themselves—ardent, alert, & mindful— putting aside greed & distress with reference to the world. I tell you, monks, that this—careful attention to in-&-out breaths—is classed as a feeling among feelings,6 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, ‘I will breathe in…&…out sensitive to the mind’; trains himself, ‘I will breathe in…&…out satisfying the mind’; trains himself, ‘I will breathe in…&…out steadying the mind’; trains himself, ‘I will breathe in…&…out releasing the mind’: On that occasion the monk remains focused on the mind in & of itself—ardent, alert, & mindful—putting aside greed & distress with reference to the world. I don’t say that there is mindfulness of in-&-out breathing in one of lapsed 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, ‘I will breathe in…&…out focusing on inconstancy’; trains himself, ‘I will breathe in…&…out focusing on dispassion’; trains himself, ‘I will breathe in…&…out focusing on cessation’; trains himself, ‘I will breathe in…&…out focusing on relinquishment’: On that occasion the monk remains focused on mental qualities in & of themselves—ardent, alert, & mindful—putting aside greed & distress with reference to the world. He who sees with discernment the abandoning of greed & distress is one who watches carefully 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 establishings of mindfulness to their culmination.”
NOTES
1. To the fore (parimukhaṁ): An Abhidhamma text, Vibhaṅga 12:1, defines this term as meaning “the tip of the nose or the sign of the mouth.” However, the term appears as part of a stock phrase describing a person engaged in meditation, even for themes that have nothing to do with the body at all, such as sublime-attitude (brahma-vihāra) meditation (AN 3:64). Thus it seems more likely that the term is used in an idiomatic sense, indicating either that mindfulness is placed face-to-face with its object, or that it is made prominent, which is how I have translated it here.
2. The commentaries insist that “body” here means the full length of the breath, but this is unlikely in this context, for three reasons: (a) The first two steps already require being aware of the entire length of the breath. Otherwise, the meditator wouldn’t know if a breath was short or long. (b) The fourth step—without further explanation—refers to the breath as “bodily fabrication.” If the Buddha were using two different terms to refer to the breath—“body” and “bodily fabrication”—in such close proximity, he would have been careful to signal that he was redefining his terms (as he does below, when explaining that the first four steps in breath meditation correspond to the practice of focusing on the body in and of itself as a frame of reference). But he doesn’t. (c) As AN 10:20 indicates, the fourth step refers to bringing the mind to the fourth jhāna, a state in which in-and-out breathing grows still (SN 36:11; AN 10:72) and the body is filled with pure, bright awareness (after awareness has been extended to be sensitive to the entire body beginning with the first jhāna (DN 2; MN 119)). Because the fourth step focuses on the stilling of the breath, there has to be a step in which the awareness is extended to fill the entire body. That would be this step.
3. “In-&-out breaths are bodily; these are things tied up with the body. That’s why in-&-out breaths are bodily fabrications.”—MN 44.
“And how is a monk calmed in his bodily fabrication? There is the case where a monk, with the abandoning of pleasure & pain—as with the earlier disappearance of elation & distress—enters & remains in the fourth jhāna: purity of equanimity & mindfulness, neither pleasure nor pain.” — AN 10:20
“When one has attained the fourth jhāna, in-and-out breaths have ceased.” — SN 36:11 & AN 9:31
4. “Perceptions & feelings are mental; these are things tied up with the mind. That’s why perceptions & feelings are mental fabrications.”—MN 44.
5. AN 9:34 shows how the mind, step by step, is temporarily released from burdensome mental states of greater and greater refinement as it advances through the stages of jhāna.
6. As this shows, a meditator focusing on feelings in themselves as a frame of reference should not abandon the breath as the basis for his/her concentration.
