If one some evil does
then do it not again and again.
Do not wish for it anew
for evil grows to dukkha.
Explanation: A person may do some evil things. But he should not keep on doing it over and over, repeatedly. He should not take delight in it. Accumulation of evil is painful.
The Story of Venerable Seyyasaka (Verse 117)
While residing at the Jetavana Monastery, the Buddha spoke this verse, with reference to the Venerable Seyyasaka. For Venerable Seyyasaka was Venerable Kaludayi’s fellow-monk. Becoming discontented with the continence required by the Religious Life, he started sexually stimulating himself. Thereafter, as often as he fell into this self-abuse, he broke the same rule. The Buddha heard about his doings, sent for him, and asked him, “Is the report true that you did such and such?” “Yes, Venerable.” “Foolish man,” said the Buddha, “why have you acted in a manner so unbecoming to your state?” In such fashion did the Buddha reprove him. Having so done, he enjoined upon him the observance of the rules. Then he said to him, “Such a course of action inevitably leads to suffering, both in this world and in the world to come.” So saying, the Buddha pronounced this Stanza.
