Man left the caves recently, he still fears darkness, lightning and has many superstitions, some codified in some bogus books like the bible and koran. He has not reigned anywhere - as a matter of fact he is waiting for gods to beam him up to heaven.
The universe is infinite. For those who perceive man as the physical organism are limited by their external senses. But for those through experience have realised than ‘MAN’ is the inner being which uses the physical body as a vehicle will discover very many secrets and realise the presence of the universal mind/power in everything which has been degraded to a single being called “God.” Many know that man is composed of body, soul and spirit in unity though some may choose not to believe it.
