[keho kahe, krishna saakshaat nara-naaraayana keho kahe, krishna haya saakshaat vaamana]
Blended reading (Sanskrit + English inline)
keho kahe, kṛṣṇa sākṣāt nara-nārāyaṇa keho kahe, kṛṣṇa haya sākṣāt vāmana
Some said that Kṛṣṇa was directly Lord Nara-Nārāyaṇa, and some called Him Lord Vāmanadeva incarnate.
