When the Lord was invoking His Sudarśana cakra and Śrīla Nityānanda Prabhu was imploring Him to forgive the two brothers, both the brothers fell down at the lotus feet of the Lord and begged His pardon for their gross behavior. The Lord was also asked by Nityānanda Prabhu to accept these repenting souls, and the Lord agreed to accept them on one condition, that they henceforward completely give up all their sinful activities and habits of debauchery, both the brothers agreed and promised to give up all their sinful habits, and the kind Lord accepted them and did not again refer to their past misdeeds.
This is the specific kindness of Lord Caitanya. In this age no one can say that he is free from sin. It is impossible for anyone to say this. But Lord Caitanya accepts all kinds of sinful persons on the one condition that they promise not to indulge in sinful habits after being spiritually initiated by the bona fide spiritual master.
