The world is like an impression left by a story says the Yoga Vasistha. This world of ours is deeply impermanent. It is less of a ground than we think — one can try to play the scientific trick of trying to recover an objective world from the fleeting impressions obtained by our senses, but we know that tactic is not going to work. None of these eternal scientific laws are going to help; in the long run we are all dead.
