Answer by Srinivasa Rao:
The term GOD is a human creation. The Bhagwad Geetha is also a human creation. Even the term "human" is a human creation😛
The truth is that we aatmas (souls) are playful/chaotic manifestations of the parmaatma (supreme soul). These words, communication, intercourse we do, is all a play (maaya) of the souls, to move along the path of least resistance, all the while clamouring to get rid of the gravity impacted manifestation (mass) into the freedom (energy).
GOD and Bhagwad Geetha are both attempts by some souls who reached a higher level of freedom, to regulate the other souls into less chaotic existence.
The real question is why does the parmaatma exist? And in what medium? Aah! The head spins crazily, let me get back to some maaya in the 4th dimension and maybe search for the 5th dimension (as in Interstellar).
