[sei naaraayana krishnera svaroopa-abheda eka-i vigraha, kintu aakaara-vibheda]
Blended reading (Sanskrit + English inline)
sei nārāyaṇa kṛṣṇera svarūpa-abheda eka-i vigraha, kintu ākāra-vibheda
Nārāyaṇa and Śrī Kṛṣṇa are the same Personality of Godhead, but although They are identical, Their bodily features are different.
