What is the essence of the Vedas?
The Vedas are the essence of creation. All that is in creation -- present, past, future, is present in a seed form in the Vedas. Don't ask me what is the essence of the essence! Vedas are called the essence!
"Saaravat vishwato mukham", i.e., Vedas are multi-faceted, multi-dimensional and the very essence of existence.
