I gained the knowledge related to what happens within ourselves after we shed our body. Also, aspects such as subtle body of humans, cows and cobras explained in a great way fascinated me, as all my life I was wondering what happens to all the animals after they shed their body and now I got my doubt and wonder clarified by reading this book. Our Life energy, Rinanubandha, Kalabhairava Karma, Kalabhairava kriya, other aspects related to rituals are all clearly explained as to why they were and are still being practised. I have already studied Karma: An Inner Engineering (A Yogi's guide to joy) & Karma: A craft to guide your destiny. Both the books were great and this book is also insightful.
