PURPORT

PURPORT
This is confirmed in Bhagavad-gita (15.15). Sarvasya caham hrdi sannivisto mattah smrtir jnanam apohanam ca. Every living being is controlled by the supreme living being, Paramatma, who resides within everyone's heart. He is the purusa, the purusa-avatara, who creates this material world. The first purusa-avatara is Maha-Visnu, and that Maha-Visnu is the plenary portion of the plenary portion of the Supreme Personality of Godhead, Krsna. Krsna's first expansion is Baladeva, and His next expansions are Vasudeva, Saṅkarsana, Aniruddha and Pradyumna. Vasudeva is the original cause of the brahmajyoti, and the brahmajyoti is the expansion of the rays of the body of Vasudeva.
"I worship Govinda, the primeval Lord, who is endowed with great power. The glowing effulgence of His transcendental form is the impersonal Brahman, which is absolute, complete and unlimited and which displays the varieties of countless planets, with their different opulences, in millions and millions of universes." (Brahma-samhita 5.40) The Supreme Personality of Godhead is thus described in Bhagavad-gita:
"By Me, in My unmanifested form, this entire universe is pervaded. All beings are in Me, but I am not in them." (Bg. 9.4)
This is the position of the plenary expansions of Krsna as the all-pervading Vasudeva, Saṅkarsana, Pradyumna and Aniruddha.
