According to Vedic civilization, after the birth of the child, there was name-giving ceremony, what kind of name. So that was calculated astrologically, that what kind of name he should be given, because the name should carry some meaning of the activities of his life. So Kṛṣṇa is named here Hṛṣīkeśa. Hṛṣīkeśa, Kṛṣṇa, in the fifteenth chapter is described that He gives direction to everyone. Sarvasya cāhaṁ hṛdi sanniviṣṭaḥ: (BG 15.15) "I am sitting in everyone's heart as Paramātmā." Realization of the Absolute Truth are three features, Brahman, Paramātmā and Bhagavān.
- vadanti tat tattva-vidas
- tattvaṁ yaj jñānam advayam
- brahmeti paramātmeti
- bhagavān iti śabdyate
- (SB 1.2.11)
Brahman, Paramātmā and Bhagavān. The same object. So the Brahman realization is impersonal realization. Just like the sun, the sun globe, and the sunshine. They are one, but the sunshine, realization of the sunshine, is not realization of the sun globe. Or realization of the sun globe is not realization of the sun god who is within the sun globe. Vivasvān. His name is Vivasvān. The present predominating Deity in the sun planet, his name is Vivasvān. And his son Manu is called Vaivasvata Manu.
