PURPORT

In this verse it is clearly indicated that the original source of everything is life. Brahma was instructed by the supreme life, Krsna. Krsna is the supreme living entity (nityo nityanam cetanas cetananam), and Brahma is also a living entity, but the original source of Brahma is Krsna. Therefore Krsna says in Bhagavad-gita (7.7), mattah parataram nanyat kincid asti dhananjaya: "O Arjuna, there is no truth superior to Me." Krsna is the original source of Brahma, who is the original source of this universe. Brahma is a representative of Krsna, and therefore all the qualities and activities of Krsna are also present in Lord Brahma.
