Words cannot do justice to this masterpiece. Not only do we get the spiritual interpretation and understanding on the different aspects of our inner and outer life, but more so it does not require us to give our interpretation of what Paramahansa Yogananda means.
He explains everything from how creation came into being, as the macro aspect and the micro our human evolution a step by step process of overcoming our lower nature.
He explains the three bodies, the Causal, Astral and the physical and what part they play in our day to day life and how we overcome them to ascend back to the supreme.
