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.
