This treatise is divided into two parts incorporating discussion and ascertainment of the science of religious endeavour, intuition and accomplishment. The first part of the treatise dwells on the various aspects of yoga, the second on the aspects of divine knowledge. The science of austere religious introspection has been widely covered in the book including significance of Yoga, Guru, diversity and non-duality etc. Likewise, it also covers divine grace and its power, philosophical and mundane aspects of sorrow and happiness, freedom from bondage, science of life at different periods of four mythological aeons etc. The treatise also establishes the fact that peace and bliss a man enjoys are self evident and spontaneous. Unfoldment of self-perception and self-knowledge also forms the subject matter of the book.
