There used to live a Paṇḍita in a village, some time back. He learnt many śāstras and accordingly always used to follow the Dharma. However he was worried about one thing. He used to wonder why everyone around him do so many pāpa-kāryas. He did not understand why knowingly people do mistakes; leave aside who do not know what is right and wrong. He used to think what is the reason for them not following the path of Dharma? He thought "in Kāśī Kṣhetram there will be a lot of Paṇḍitas and Jṇānis. I will discover the answer to my question through discussions with them. Also what can be better than having Viśveśvara Darśanam?"
He started walking to the divya Kṣhetram and met a vyāpāri on his way. They exchanged their identities and started travelling together. The vyāpāri, Vīrayya, told that he was going to do leather bussiness in the near by village's weekly pradarśinī. The Paṇḍita also told why he was going to the great Kāśī Kṣhetram. After sometime, Vīrayya told to the Paṇḍita:
"I have a gold piece of the size of an egg. I am thinking of giving it to some Paṇḍita as dānam". The Paṇḍita said "please do it; it will give you some Puṇyam". Vīrayya told "But I want to give only to a Paṇḍita and …" The Paṇḍita thought "There is nothing wrong if I take the dānam. Then I can take a vehicle and easily reach Kāśī Kṣhetram. Also I will have enough for my food arrangements". So he told Vīrayya that he is ready to take the dānam. Vīrayya was happy and told "but I have one condition. I will give it to a Paṇḍita who comes to my house, eats and then with tāmbūlam I will give this suvarṇam as dakṣhiṇa". The Paṇḍita thought that he had some Anuṣhṭhānas, for doing them he has to follow some niyamas and hence he cannot eat in Vīrayya's house. But then Vīrayya is offering a huge sum of money. If he gets the money he can do his kuṭumba-poṣhaṇa nicely. Also he thought that if he is not going to take, someone else will take. For every pāpam there is prāyaścittam. He thought "I am going to the great Kāśī Kṣhetram. I will do some prāyaścittam there." Thinking like this the dhana-kāṇKṣha of the Paṇḍita grew and finally told Vīrayya that he is willing to take the dānam, out of his pralobham.
After walking for a while, Vīrayya told "O Paṇḍita! Now you need not go to Kāśi. Because you already got the answer to your question". The surprised Paṇḍita said "and what is the answer?" Vīrayya continued "You have some niyamas to be followed. But you were ready to break them. So suvarṇa-kāṇKṣha made you do a pāpakaryam. Same is the reason with everybody. Everybody in order to get some or the other gain step out of their sva-dharmam".
Paṇḍita was shocked to hear the words of Vīrayya. Vīrayya continued "not only that, the pāpam of a pāpakāryam is shared by four: the person who does, the person who makes one to do, the person who praises the one who does and the person who does not say it is wrong (basically one who keeps quite). Similar is the case with Puṇyam. So I do not want to share pāpam with you. Even though you are ready for doing it, I will not support you". Saying this Vīrayya left and the Paṇḍita was surprised by the niśita-buddhi, cāturyam and Jṇānam regarding pāpācaraṇa of Vīrayya.
Durguṇam to be unlearnt: Pralobham
The main reason for a person to deviate from his niyamas and Dharmam (knowingly) is Pralobham. One must be very careful to avoid it.
