thag.3.11 Theragatha

Upāli

One newly gone forth,
who has left their home out of faith,
should mix with spiritual friends,
who are tireless and pure of livelihood.
One newly gone forth,
who has left their home out of faith,
a mendicant staying in the Saṅgha,
being wise, would train in monastic discipline.
One newly gone forth,
who has left their home out of faith,
skilled in what is appropriate and what is not,
would wander undistracted.
