Dhamma Verses (Dhammapada, KN 2)

20: The Chapter about the Path – 247
Undertaking the seers’ path
Ven. Moggallāna saw a ghost with a pig’s head and reported it
to the Buddha who explained that in a previous life he was
someone who broke up a sincere friendship, and after arising
in Avīci, the hell of relentless suffering, was later reborn as a
ghost with a pig’s head because of his misdeed, and then the
Buddha spoke this verse.
281. Vācānurakkhī manasā susaṁvuto,
kāyena ca akusalaṁ na kay i rā,
ete tayo kammapathe visodhaye,
ārādhaye maggaṁ isippaveditaṁ.
Verbally guarded, well-restrained in mind,
not doing demerit with the body,
one should purify three paths of action,
and undertake the path shown by seers.
