Dhamma Verses (Dhammapada, KN 2)

25: The Chapter about Monastics – 303
The true monastic
Two friends retired from the world and became monks
together; one day, after bathing, they saw two geese flying
through the air, and one of the monks said he could hit one of
the geese in both eyes, and threw a pebble which hit its mark
and brought the goose down; when the Buddha heard about it
he taught them a Jātaka about scrupulous laymen, and then
taught them further with this verse.
362. Hatthasaṁyatŏ pādasaṁyato,
vācāya saṁyatŏ saṁyatuttamo,
ajjhattarato samāhito,
eko santusito: tam-āhu bhikkhuṁ.
One who controls his hands, controls his feet,
controls his speech, controls the mind supreme,
with delight, composure, solitary,
content: that one is called a monastic.
