So Durvāsā Muni, he was a great yogī, and he became very much envious, that "Here is a person who is a gṛhastha and a kṣatriya, he is not even a brāhmaṇa, and he does not practice anything. He is always engaged in his royal activities, and this man is so famous as a great person, great devotee. So I'll chastise him. I'll show." So he wanted to pick up some quarrel with Ambarīṣa Mahārāja, and on dvādaśī day he approached there with sixty thousand disciples, and he said, "Mahārāja, arrange for our prasādam. We . . ." "Yes, welcome." But his purpose was different. So he went to take bath in the Ganges and Yamunā, and then he came late. In the meantime he had to observe dvādaśī-pāraṇa. With the advice of the brāhmaṇas he took little water. The brāhmaṇas advised, "Mahārāja, water is food and no food. It has no actually food value. So your guest has not returned as yet. You can take little water and observe the completion of dvādaśī." So he did it, and Durvāsā came very angry, that "I am your guest, and you have taken food?" That is not food; little water. So he wanted to chastise him. He created a big giant to kill the Mahārāja.
So immediately Kṛṣṇa's promise . . . Kaunteya pratijānīhi na me bhaktaḥ praṇaśyati (BG 9.31). Immediately sudarśana-cakra came and killed that demon immediately, and then he pursued Durvāsā Muni. Durvāsā Muni first of all approached Lord Śiva because he was devotee of Śiva: "Please give me protection." He said, "Oh, it is not possible for me. If sudarśana-cakra is after you, I cannot do anything." Then similarly, he approached Brahmā. So he also said, "No, this is not possible." Then he was so powerful that he approached Lord Viṣṇu even, personally, in the Vaikuṇṭhaloka. He refused to help him. He said, "Durvāsā Muni, unless you beg pardon from Ambarīṣa Mahārāja, there is no question of excusing you. The sudarśana-cakra will not excuse." Therefore Vaiṣṇava aparādha is very, very offensive. You should be very careful. Caitanya Mahāprabhu has warned Vaiṣṇava aparādha, hātī mata. Vaiṣṇava aparādha, offense at the feet of Vaiṣṇava, is exactly like mad elephant. If a mad elephant enters your garden, then he spoils everything. This has been given. Vaiṣṇava aparādha means hātī mātā. Mātā means mad, and hātī means elephant. So we should be very, very careful not to commit any offense at the feet of Vaiṣṇava. Vaiṣṇava does not take any offense. He does not care who is offender, but Kṛṣṇa takes care. Kṛṣṇa will never tolerate if a person is Vaiṣṇava aparādha. Mind that. Just like a big man: you can offend him, he doesn't mind. But if he does something harmful to his child, so he becomes very angry.
