Saṁyutta Nikāya — Discursos Conectados — 54.5 — Fruits (2nd)

1“Mendicants, when mindfulness of breathing is developed and cultivated it’s very fruitful and beneficial. And how is mindfulness of breathing developed and cultivated to be very fruitful and beneficial?

2It’s when a mendicant—gone to a wilderness, or to the root of a tree, or to an empty hut—sits down cross-legged, sets their body straight, and brings mindfulness to the present.

3Just mindful, they breathe in. Mindful, they breathe out. …

4They practice like this: ‘I’ll breathe in observing letting go.’ They practice like this: ‘I’ll breathe out observing letting go.’

5Mindfulness of breathing, when developed and cultivated in this way, is very fruitful and beneficial.

6When mindfulness of breathing is developed and cultivated in this way you can expect seven fruits and benefits. What seven? You attain enlightenment early on in this very life. If not, you attain enlightenment at the time of death. If not, with the ending of the five lower fetters you’re extinguished in between one life and the next … you’re extinguished upon landing … you’re extinguished without extra effort … you’re extinguished with extra effort … you head upstream, going to the Akaniṭṭha realm … When mindfulness of breathing is developed and cultivated in this way you can expect these seven fruits and benefits.”
