How can I chant his greatness from whom have sprung Brahmā, Rudra, Chandra, Indra, the Maruts, the Aswins, the Vasus and the Adityas—of whom but, a small portion is the whole universe, which is destined to represent his essence and whose nature, primitive or derived is beyond the conception of Brahmā and other immortals. How can I approach him who is worshipped by the celestials with incense and flowers culled from the groves of Nandana?

In plain words: Kaliya asks how he could ever praise the one from whom all the gods came, including Brahma, Rudra (Shiva), Indra and others. The whole universe is only a small part of Krishna. Even Brahma cannot understand his nature.
