sn.52.5 Saṁyutta Nikāya (Linked Discourses)

At Thorny Wood (2nd)

At Sāketa.
Sāriputta said to Anuruddha:
“Reverend Anuruddha, what things should a mendicant who is an adept enter and remain in?”
“Reverend Sāriputta, a mendicant who is an adept should enter and remain in the four kinds of mindfulness meditation.
What four?
It’s when a mendicant meditates by observing an aspect of the body—keen, aware, and mindful, rid of desire and aversion for the world.
They meditate observing an aspect of feelings …
mind …
principles—keen, aware, and mindful, rid of desire and aversion for the world.
A mendicant who is an adept should enter and remain in these four kinds of mindfulness meditation.”
