Srimad Bhagavatam 10.1.20
tatra gatva jagannatham
After reaching the shore of the ocean of milk, the demigods worshiped the Supreme Personality of Godhead, Lord Vishnu, the master of the whole universe, the supreme God of all gods, who provides for everyone and diminishes everyone’s suffering. With great attention, they worshiped Lord Vishnu, who lies on the ocean of milk, by reciting the Vedic mantras known as the Purusha-sukta.
The demigods, such as Lord Brahma, Lord Siva, King Indra, Candra and Surya, are all subordinate to the Supreme Personality of Godhead. Aside from the demigods, even in human society there are many influential personalities supervising various businesses or establishments. Lord Vishnu, however, is the God of gods (paramesvara). He is parama-purusha, the Supreme Being, Paramatma. As confirmed in the Brahma-samhita (5.1), isvarah paramah krishnah sac-cid-ananda-vigrahah: “Krishna, known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body.” No one is equal to or greater than the Supreme Personality of Godhead, and therefore He is described here by many words: jagannatha, deva-deva, vrishakapi and purusha. The supremacy of Lord Vishnu is also confirmed in Bhagavad-gita (10.12) in this statement by Arjuna:
param brahma param dhama
pavitram paramam bhavan
purusham sasvatam divyam
adi-devam ajam vibhum
“You are the Supreme Brahman, the ultimate, the supreme abode and purifier, the Absolute Truth and the eternal divine person. You are the primal God, transcendental and original, and You are the unborn and all-pervading beauty.” Krishna is adi-purusha, the original Personality of Godhead (govindam adi-purusham tam aham bhajami **). Vishnu is a plenary expansion of Lord Krishna, and all the vishnu-tattvas are paramesvara, deva-deva.
