Branch of philosophy that deals with the first principles of things, including abstract concepts such as being, knowing, substance, cause, identity, time, and space... The Hindu concept of "Heaven and "Hell" are not quite the same as what we imagine them to be in popular culture today..... The western concepts of "Hell and Heaven" roughly correspond to the Hindu equivalent of intermediate states between birth and rebirth."The rebirth of a soul in a new body"We believe in our own thought..This is the essence of freedom.
