In the Bhagavad Gita, Lord Krishna tells Arjuna that ‘Of the Adityas I am Vishnu, of the Vedas I am the Samveda, of the Gods I am Indra, and among the Rudras I am Shankara. Why does he prefer one over the other?
He always said, ‘I am the best’. So he goes for the best. So among the Vedas, Samveda is considered to be the best because it is musical. It is the mother of all music, harmony, love and devotion. So Krishna prefers one over another.
These are His preferences. He does not say other things are of lesser importance or are no good, no, not at all! He just says, ‘I am this’.
It is like sometimes you got to a restaurant and pick up certain things and say, ‘I like it’. That doesn’t mean you do not like the other things.
