Tuvaṭakasuttaṃ [Snp 4.14, PTS 179–182]

How, having seen, is a monk extinguished, not clinging to anything in the world?"

"With wisdom one should keep in check all that is 'I am';

Whatever cravings there are internally,

For the removal of those, one should always train mindfully.

One should not make strength by that, for that is not called quenching by the good.

Touched by various forms, one should not stand imagining oneself.

For one internally at peace, there is no self, whence non-self?

So established, without longing, a monk should not create excess anywhere."

Tell the practice, venerable one, the principal monastic code or else concentration."

And one should not covet flavours, nor should one cherish anything in the world.

And should not yearn for existence, and should not tremble among fearful things.

Having obtained, one should not make storage, nor should one be distressed not obtaining those.

Then a monk should dwell in seats and beds that are quiet.

One should abandon lethargy, deceit, laughter, play, sexual intercourse together with adornment.

Nor interpreting animal cries, nor inducing conception, nor medical treatment - one devoted to me should not pursue these.

He should dispel greed together with stinginess, wrath and slander.

And one should not be attached in the village, one should not cajole people out of desire for gain.

He should not train in impudence, nor should he speak contentious talk.

Then by livelihood, by wisdom, by moral rules and austerities, one should not despise another.

One should not reply to them with harshness, for the peaceful do not make opposition.

Having known peace as 'this is peace', one should not be negligent in the teaching of Gotama.

Therefore, in that Blessed One's Dispensation, one should always, diligent, pay homage and train."
