In the Gita, in plain and simple language, it is stated that Sri Krsna is the Supreme Personality of Godhead. There is none equal to or greater than Him. … He is the root of the impersonal Brahman and Paramatma; the Supersoul in every entity is His plenary portion. He is the fountainhead of everything, and everyone is advised to surrender unto His lotus feet.
