法苑珠林 34.16

34.16

Eighth, 'mindfulness of ānāpāna' means with concentrated essence to be mindful of ānāpāna: when the breath is long, contemplating and knowing, 'My breath is now long'; when the breath is short, one should also contemplate and know, 'My breath is now short'; when the breath is extremely cold or extremely hot, one should also contemplate and know, 'My breath is now cold or hot.' Discerning inhalation and exhalation, counting the length of the breath, eliminating all chaotic thoughts, one of oneself attains nirvāṇa. Never departing from ānāpāna, one then obtains merit. This is termed 'mindfulness of ānāpāna.'
