The Advantages of the Mindfulness of Breathing Meditation
From the Diipa Sutta (the Discourse on the Lamp), SN 54.8
"… I too, monks, before my awakening, when I was an unawakened bodhisatta, frequently remained with this abiding. When I frequently remained with this abiding, neither my body was fatigued nor were my eyes, and my mind, through lack of clinging/sustenance, was released from fermentations.
"So if a monk should wish: 'May neither my body be fatigued nor my eyes, and may my mind, through lack of clinging/sustenance, be released from fermentations,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May my memories & resolves related to the household life be abandoned,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I remain percipient of loathsomeness in the presence of what is not loathsome,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I remain percipient of unloathsomeness in the presence of what is loathsome,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I remain percipient of loathsomeness in the presence of what is not loathsome & what is,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I remain percipient of unloathsomeness in the presence of what is loathsome & what is not,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I — in the presence of what is loathsome & what is not — cutting myself off from both — remain equanimous, mindful, & alert,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I — quite secluded from sensuality, secluded from unskillful qualities — enter & remain in the first jhana: rapture & pleasure born from seclusion, accompanied by directed thought & evaluation,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I, with the stilling of directed thoughts & evaluations, enter & remain in the second jhana: rapture & pleasure born of concentration, unification of awareness free from directed thought & evaluation — internal assurance,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish, 'May I, with the fading of rapture, remain equanimous, mindful, & alert, sense pleasure with the body, and enter & remain in the third jhana, of which the noble ones declare, "Equanimous & mindful, he has a pleasant abiding,"' then he should attend closely to this very same concentration through mindfulness of in-&-out breathing.
"If a monk should wish, 'May I, with the abandoning of pleasure & pain — as with the earlier disappearance of elation & distress — enter & remain in the fourth jhana: purity of equanimity & mindfulness, neither-pleasure-nor-pain,' then he should attend closely to this very same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I, with the complete transcending of perceptions of (physical) form, with the disappearance of perceptions of resistance, and not heeding perceptions of diversity, (perceiving,) 'Infinite space,' enter & remain in the dimension of the infinitude of space,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I, with the complete transcending of the dimension of the infinitude of space, (perceiving,) 'Infinite consciousness,' enter & remain in the dimension of the infinitude of consciousness,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I, with the complete transcending of the dimension of the infinitude of consciousness, (perceiving,) 'There is nothing,' enter & remain in the dimension of nothingness,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I, with the complete transcending of the dimension of nothingness, enter & remain in the dimension of neither perception nor non-perception,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"If a monk should wish: 'May I, with the complete transcending of the dimension of neither perception nor non-perception, enter & remain in the cessation of perception & feeling,' then he should attend carefully to this same concentration through mindfulness of in-&-out breathing.
"When concentration through mindfulness of in-&-out breathing is thus developed, thus pursued, then if he senses a feeling of pleasure, he discerns that it is inconstant, not grasped at, not relished. If he senses a feeling of pain, he discerns that it is inconstant, not grasped at, not relished. If he senses a feeling of neither-pleasure-nor-pain, he discerns that it is inconstant, not grasped at, not relished. If he senses a feeling of pleasure, he senses it disjoined from it. If he senses a feeling of pain, he senses it disjoined from it. If he senses a feeling of neither-pleasure-nor-pain, he senses it disjoined from it. When sensing a feeling limited to the body, he discerns that 'I am sensing a feeling limited to the body.' When sensing a feeling limited to life, he discerns that 'I am sensing a feeling limited to life.' He discerns that 'With the break-up of the body, after the termination of life, everything that is experienced, not being relished, will grow cold right here.'
"Just as an oil lamp burns in dependence on oil & wick; and from the termination of the oil & wick — and from not being provided any other sustenance — it goes out unnourished; in the same way, when sensing a feeling limited to the body, he discerns that 'I am sensing a feeling limited to the body.' When sensing a feeling limited to life, he discerns that 'I am sensing a feeling limited to life.' He discerns that 'With the break-up of the body, after the termination of life, everything that is sensed, not being relished, will grow cold right here.'"
