Within the existence of the universe, we are born and die. Many civilizations come up and disappear. If civilizations come up, living beings evolve and they disappear back again. All that happens in one day of brama. At the night, the entire physical universe is absorbed back into maya. Then only consciousness and maya exists. And then again, the whole cycle starts. Su a stupendous, mind blowing conception, stretching across billions and billions of years,. Millions of lifetimes, millions of universes and endless stars, planets, galaxies. Sas very extraordinary vision.
