In the ancient Vedanta tradition of Samadhi Sadhana, the Masters have advised us to take recrouse to 'Drishyanu vidhi' and 'sabdanu vidhi' forms of 'Savikalp samadhi' in the beginning. This leads us naturally and unfailingly to "Nirvikalp Samadhi" the ultimate fulfillment. How the sacred symbol OM facilitates these three kinds of meditation is briefly explained in simple language in this Samvit exposition. A Valuable guide for all Serious seekers.
