Vrajendra-nandana, the idea of accepting the Lord as son . . . Mahārāja Nanda accepted Kṛṣṇa as his son, similarly Śacīdevī accepted Lord Caitanya as his (her) son. So both of Them are the one. So Narottama Dāsa Ṭhākura says: "The same Vrajendra-nandana, Kṛṣṇa, has now appeared as Lord Caitanya, as the son of Śacī. And the same Balarāma has become Nitāi."
And what is Their business? The business is pāpī-tāpī jata chilo: "They are claiming all kinds of sinful conditioned souls." Their only business is. Because in this age, Kali-yuga, you cannot find any perfectly pious man or saintly person. Everyone is addicted to so many sinful activities.
So pāpī-tāpī yata chilo, hari-nāme uddhārilo. Simply by distributing this chanting, He claimed everyone, however fallen he may be. "Come on, chant Hare Kṛṣṇa and become delivered." You see? So nice thing. Pāpī-tāpī yata chilo, hari-nāme uddhārila. What is the evidence that He has? Ta 'ra sākṣī jagāi and mādhāi. Jagāi-Mādhāi, they were two brothers, debauch number one. You see?
They were all kinds of sinful affairs. They were drunkard, they were woman hunter, meat-eater, so many things. And, of course, they were born in a very high Brāhmin family, but bad association, they became like that. Similarly, at the present age, this human society, although they are coming from the Āryan family, very nice family, but due to association the only environment is there's woman and intoxication, meat-eating, and gambling. That's all.
