A work written originally in Urdu by Ram Chandra (Lalaji) Maharaj, the book is a treatise on the chakra vidya or the science of spiritual chakras or subtle centres. This volume presents an English translation of the work which was published in Hindi in 2009 based on his original handwritten manuscripts. The work deals with various aspects of spiritual life, offering a synthesis of Hindu philosophy and Sufi thought. It gives a glimpse of the contribution of the various saints and liberated souls while revealing the secrets of brahma vidya or esoteric knowledge. It showcases his views on satguru, self-restraint, the physical existence, the realms of mind and hridya, his description of chakras, meaning of liberation and attaining it, and the consequences of ignorance.
