Sri Caitanya Mahaprabhu advised the wealthy Hindu Buddhimanta Khan to atone for having been ‘made a Muslim’ by giving up his community, social and family life and by going to Vrindavana and chanting constantly the Lord’s Holy Names. He writes that “one who fully surrenders to the Supreme Personality of Godhead is freed from all sins (aham tvam sarva-papebhyo moksayisyami). From the moment he fully surrenders to Sri Krsna, even the most sinful person is freed.” (from the purport to 9.15.41)
