An introductory book to Sahaja Yoga meditation, a practice created by Shri Mataji Nirmala Devi. Sahaja Yoga meditation, which is free and open to everyone, enables the opening of a new dimension of human awareness - collective consciousness - that can be achieved through the self-knowledge and enlightenment engendered by Self-realization. The present book includes a guided meditation dedicated to the experience of Self-realization, knowledge about the seven chakras and three channels of energy in our subtle system, references to scientific research, personal accounts of spiritual experiences and events that lie outside the ordinary, and testimonials from Sahaja Yoga practitioners from around the world on how this meditation system has profoundly improved their lives. What reviewers say: "Know Thyself is phenomenally well written, there's an elegance, a style to it that sets it apart from most Sahaja writings." -- Alan W., New York, USA. "I feel so much larger and much more informed by having read the book... Having everything in one place in such an organized fashion was priceless for me." -- Clem S., Texas, USA. "This book inspires me like Plato's account of Socrates did in my early teens. It is infused with love for humanity. The seeker of truth in me is reawakened, and new readers will also surely come to know that eternal wellspring within." -- Victor V., Piacenza, Italy. "This is one of the best books I have read in Sahaja Yoga, also a go-to book for even experienced practitioners. It’s just excellent. This is the only book I can think of which I can hand over to a seeker of spiritual truth with confidence. This will be a go-to reference book for generations to come." -- Venkat R., Oklahoma, USA.
