Prabhupāda: There is a proverb, kalo brāhmaṇa kota śūdra bete mussulman kalki chele busi... (?) A brāhmaṇa, black... Brāhmaṇa's another name is śukla, white. So as soon as a brāhmaṇa is black then he's (indistinct) kalo brāhmaṇa. Kota śūdra, and śūdra, just like African, if they become white there is something mystery. Kalo brāhmaṇa kota śūdra bete mussulman, Mohammedan, because Mohammedan means the Afghans, they are very tall, so a Mussulman is dwarf, a brāhmaṇa is black, the śūdra is white, kalo brāhmaṇa kota śūdra bete mussulman and kalki chelo, that means the bastard and (indistinct) ...these are all of the same class.
