manye - I think; kṛṣṇam - Kṛṣṇa; ca - and; rāmam - Balarāma; ca - and; prāptau - obtained; iha - on this planet; sura - of demigods; uttamau - two of the most elevated; surāṇām - of the demigods; mahat - great; arthāya - for a purpose; gargasya - of the sage Garga; vacanam - the statement; yathā - as.

In my opinion, Kṛṣṇa and Balarāma must be two exalted demigods who have come to this planet to fulfill some great mission of the demigods. Such was foretold by Garga Ṛṣi.
