Srimad Bhagavatam Canto 07, Chapter 03, Text 29

SB 7.3.29

tvam isise jagatas tasthusas ca
 pranena mukhyena patih prajanam
cittasya cittair mana-indriyanam
 patir mahan bhuta-gunasayesah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Your Lordship, being the origin of the life of this material world, is the master and controller of the living entities, both moving and stationary, and you inspire their consciousness. You maintain the mind and the acting and knowledge-acquiring senses, and therefore you are the great controller of all the material elements and their qualities, and you are the controller of all desires.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
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 kiñcid asti dhanañjaya: “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.
