Laws of Physics have been formulated for physical bodies of this world. The question arises whether these laws can be applicable to non – physical bodies also, about which the vedic mythology seems to be dealing with. The present paper takes as an example the second law of thermodynamics according to which the entropy or the degree of disorder of any system in this world is constantly increasing. In other words, the world is going towards a state where it will be impossible to take any useful work from its available energy. As an example, the steam of a steam engine can be put to useful work until the steam is bound in its cylinder. As soon as the steam goes out and spreads, no useful work can be taken from it. The steam engine can be compared to the system of consciousness. The driver of this engine is vedic seer or rishi who knows where, when and how the engine of consciousness has to be put in the state of low or high entropy and the steam has been given the name rasa. Various functions of the engine have been embodied in the form of  7 meters or Chhandas. The efficiency of the engine is measured by Trishtup Chhandah. The lowest efficiency of this engine is when every event of this world happens as a play of dice. But Einstein thinks that God does not play the dice.
