3.8.p2

It was then that the Bhagavān addressed the monks, “One should cultivate one thing and disseminate one thing. After cultivating this one thing, they’ll become well known and achieve a great reward and all good and complete attainments. They’ll attain the sweet-tasting dew and arrive at the unconditioned state. They then will achieve spiritual knowledge, dispel their confused ideas, win the fruits of the ascetic, and bring about nirvāṇa themselves. What’s this one thing? It’s called recollecting breathing.”
