Jagai-Madhai were born in nice brahmana family, but due to bad association, they became drunkard, prostitute hunters, gambler and meat-eater. So they were simply creating disturbance on the street, and there was a crowd. Lord Nityananda saw the crowd and inquired from persons, “What is this crowd?” Lord Nityananda and Haridasa Thakura were out for preaching. So people informed that “There are two brothers, most sinful, and they are creating disturbance. So there is crowd.” So immediately Nityananda Prabhu said, “Why not deliver these two brothers immediately? Then it will be a great credit for Caitanya Mahaprabhu.”
This is preacher. He is thinking the credit of the master, not for Himself. He risked His life. And the Jagai-Madhai brothers hurt Him on the head by throwing a stone. So blood also came out, but still, they said, “All right, it is all right. You have hurt Me. Blood is oozing out. That doesn’t matter. You chant Hare Krsna.” That is preaching. Not that I remain safety and chanting Hare Krsna. No. We have to go out, meet the Jagai-Madhai. That is Caitanya Mahaprabhu’s mission. Because the world is full of Jagai-Madhai.
So when Lord Caitanya Mahaprabhu became very angry because these people, these two brothers, injured Nityananda Prabhu, so He became firelike. So you should be firelike when a Vaisnava is insulted. Not that at that time trnad api sunicena, to become straw. No. You should be fire when Visnu and Vaisnava is insulted. So Caitanya Mahaprabhu showed this example. He became very, very angry: “I shall kill these two brothers immediately. Nonsense.”
So Nityananda Prabhu entreated, “Oh, My dear sir, this time You have promised not to accept any weapon. In Your incarnation as Lord Ramacandra, You took up weapon. As Krsna also, You took a weapon. But this time You wanted to deliver these poor souls. So don’t kill them. Excuse them. Accept them.” This is Nityananda Prabhu’s business, guru’s business. So Lord Caitanya simply asked them, “Now if you…” They also in the meantime fell down on the lotus feet of Lord Caitanya, that “We are so sinful. We have done wrong. Kindly excuse us.”
