@AnilKumar Another prominent Vedic reference to Vishnu's supremacy is in the Aitareya Brahmana of the Rig Veda, which begins with the words "Agni is the lowest of the gods, Vishnu the highest".

@AnilKumar Anyway there's no point fighting here over which god is supreme. I just cited these quotes to answer your question about whether the Vedas ever state it.
