The Glory Of Our Soul

Vedanta teaches men to have 
faith in themselves first. 
As certain religions of the world 
say that a man who does not believe
in a Personal God outside himself
is an atheist, so Vedanta says that
a man who does not believe in the 
God within himself is an atheist. 
Not believing in the glory of our own soul 
is what Vedanta calls atheism.
