Blended reading (Sanskrit + English inline)
svayaṁ bhagavān kṛṣṇa, viṣṇu-paratattva pūrṇa-jñāna pūrṇānanda parama mahattva
Kṛṣṇa, the original form of the Personality of Godhead, is the summum bonum of the all-pervading Viṣṇu. He is all-perfect knowledge and all-perfect bliss. He is the Supreme Transcendence.
