This book is an amalgamation of modern sciences of physiology & psychology and ancient sciences of tantra & vedanta. It teaches the reader how he/she is practically in-charge of his/her life and how to technically take control of his/her life. The book covers 9 chapters with practices mentioned at the end of each chapter. The book explains in a practical & scientific way that just by understanding the functions of the mind, prana (energy) and body, one can take precise control of his/her life and become whatever he/she wants. No one has ever provided such a practical and scientific explanation of how life works.
