tasmin brahmany advitiye
brahma-rudrau ca bhutani
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Lord continued: One who is not in proper knowledge thinks that demigods like Brahma and Siva are independent, or he even thinks that the living entities are independent.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The living entities, including Brahma, are not independently separated, but are counted within the marginal potency of the Supreme Lord. The Supreme Lord, being the Supersoul in every living entity, including Lord Brahma and Lord Siva, is directing everyone in the activities of the material modes of nature. No one can act independently of the sanction of the Lord, and therefore, indirectly, no one is different from the Supreme Person certainly not Brahma and Rudra, who are incarnations of the material nature’s modes of passion and ignorance.
