Originally written as a series of letters to close disciples, this text presents sixteen practical lessons for the soul seeking enlightenment. An inspiring introduction to the system of Kriya Yoga, each chapter focuses on a specific aspect of the spiritual study, direction, self-discipline, healing and keeping the body healthy, balancing the emotions, quieting the mind, and expanding the horizon of awareness.
