34.16

第八念安般者。謂專精念安般者。若息長時觀知我今息長。若復息短亦當觀知我今息短。若息極冷極熱亦當觀知我今息冷熱。出入分別數息長短。除諸亂想自致涅槃。不離安般便獲功德。是名念安般。

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.'
