A Monk Should Destroy All Passions

Not by rules and observances,
not even by much learning, nor by gain of absorption,
nor by a life of seclusion, nor by thinking,
“I enjoy the bliss of renunciation,
which is not experienced by the worldling” should you,
O monks, rest content, until the utter destruction of cankers (Arahantship) is reached.
– Dhammapada XIX. Dhammatthavagga: The Just :: Verse 271 – 272
