“Na Tam Kamm Katam Sadhu,
Yeh Kutva Anutappati.”
– Tathagata Buddha
That is, it is not right to do that work, which you have to repent doing.

Once upon a time, Tathagata Buddha used to live in Shravasti when an incident happened. At that time a farmer was working in his field. The thieves had distributed the stolen goods in the same field. Thieves forgot in that field a bag full of stolen goods. The farmer saw the bag full of money. He got greedy. He hide the bag in his field.

The one whose money was stolen, seeing the footprints of the thieves, reached the farmer’s field. From there he followed in the footsteps of the farmer and reached that bag. He complained to the king. The king’s soldiers caught the farmer and sentenced him to death for theft. When the soldiers started taking him to the place of slaughter, he was muttering – “Happy! Look at that poisonous snake. Reverend I have seen that poisonous snake, it is very poisonous indeed.”

The king wanted to know the secret of the farmer’s murmur. Then God told the truth of the incident that the farmer had not actually stolen, because greed, he had hidden the stolen bag. The farmer was now remorseful because of his karma. Knowing the truth, the king left the farmer.

In the context of this incident Buddha said-
The intelligent person should not do the work which one has to repent for doing. Because, that work is not a well done work, due to which a person is unhappy and the result of which has to be suffered by weeping.
“Yass Assumukho Rodan,
Vipakam Patisevati.”

If that farmer –
“Adinnadana Veramani Sikkhapadam Samadiyami” – had followed the modesty, he would not have had to suffer torture.

Tathagatha Buddha said in Venuvan, Rajagriha-
“Tancha Kammam Katam Sadhu,
Ya Katva Nanutappati.”
Meaning – It is okay to do that work, which you do not have to regret doing.
