saṅkīrṇa-yonayaḥ pūtā ye bhaktā madhusūdane
saṅkīrṇa-yonayaḥ pūtā ye bhaktā madhusūdane |
mleccha-tulyāḥ kulīnās te ye na bhaktā janārdane ||
(Skanda Purāṇa; cited in Hari-bhakti-vilāsa: 10.129)
“Those of mixed caste who are bhaktas of Madhusūdana are pure. Those who are of noble family but not bhaktas of Janārdana are equal to mlecchas [i.e., those of the very lowest caste].”
