Lila means play. Back in the 1980s while we were in India, friends of mine in the ashram made the following Veda Lila video. The Veda is an unbounded field, an unbounded ocean of pure consciousness interacting with itself. The Veda is nature. It is the underlying basis of all existence. To know the Veda is to know the true nature of life and existence. It is like the seed that births the entire tree.
Consciousness, the Knower, Rishi, becomes conscious of itself and perceives itself as other, the Known Chhandas. The process is of Knower becoming aware of Known is called Devata. So those three things are born: Rishi, Devata, and Chhandas. Those three things taken together are called the wholeness or Samhita value. This process goes on and on creating the play of the Veda, Veda Lila. One becomes three and goes on within and to infinity.
