Philosophy of Liberation is a intriguing book, providing some surprisingly technical details on the Yoga of Sound -- Surat Shabd Yoga Meditation ("Nadanu Sandhana"), as well as the Yoga of Light, referred to in their terminology as "Drshti Yoga", Yoga of Vision). Anyone interested in developing their own successful daily meditation practice will greatly benefit from the wisdom and depth of, "Philosophy of Liberation", as it systematically covers all aspects of the philosophy of the Path of the Masters (Sant Mat, Radha Soami, Surat Shabd Yoga) and the technical details of spiritual practice rarely ever seen in print from any source outside of India. This book is remedial Sant Mat 101 for those who seek to come to a deeper understanding of the teachings of Masters and develop their own meditation practice. Philosophy of Liberation is not light reading, and that is precisely what I like about it! It is quite literally, THE MANUAL of Sant Mat -- one of the best books ever written about traditional Sant Mat Mysticism and the Radhasoami Faith. Jai Guru, Jai Sat Naam, Radhasoami, James
