Madhya 17.60

Actually a sannyasi or a brahmana will not accept an invitation extended by a person born in a lower family. However, there are many devotees who are raised to the platform of brahmana by their initiation. These people are called sudra-mahajana. This indicates that one who is born in a non-brahmana family has accepted the brahmana status by initiation. Such devotees extended invitations to Balabhadra Bhattacarya. A Mayavadi sannyasi will accept an invitation only from a brahmana family, but a Vaisnava does not accept an invitation from a brahmana if he does not belong to the Vaisnava sect. However, a Vaisnava will accept an invitation from a brahmana or sudra-mahajana if that person is an initiated Vaisnava. Sri Caitanya Mahaprabhu Himself accepted invitations from sudra-mahajanas, and this confirms the fact that anyone initiated by a Vaisnava mantra can be accepted as a brahmana. One can accept an invitation from such a person.
