That is Caitanya Mahāprabhu. He delivered Jagāi-Mādhāi. They were very sinful. Sinful means they were born in a respectable brāhmaṇa family, but by bad association they became drunkard, woman-hunter, cheater and plunderer, like that. That is sinful. So Caitanya Mahāprabhu delivered them. Then how delivered them? Caitanya Mahāprabhu made them promise that "You will not do any more all these things." They said, "Yes, we promise. We shall not do." "Then you are delivered." Similarly, by chanting Hare Kṛṣṇa mantra, all the sinful activities are excused, but you don't commit it again. Therefore we are prescribing . . . along with chanting of Hare Kṛṣṇa mantra, we are asking our disciples, "No illicit sex, no meat-eating, no intoxication, no gambling." If you save yourself from these four pillars of sinful activities and chant Hare Kṛṣṇa mantra—not very much, only sixteen rounds minimum—then you are saved from the hellish condition of life for which Parīkṣit Mahārāja was so disturbed and he was asking, "How to save these people from this hellish condition of life?"
So this will be described more and more. The book is there, Bhāgavata. You can read. We are . . . we have published so many Śrīmad-Bhāgavatam edition, nicely explained in English. So they are being accepted even educated circle, school, college, and big, big professors. So you also try to read this Bhāgavatam, and don't commit sinful activities, the four things, and chant Hare Kṛṣṇa. Then your life is saved from hellish condition of life.
