Sri Ramkrishna Das explains the significance of nama-japa in the sadhana of Sri Aurobindo's Integral Yoga and provides detailed instructions on the method of its practice. The author discusses in careful detail the many obstacles and difficulties with which the sadhak of this yoga is confronted and points out the way for overcoming them with the help of the Mother's name. He writes: "Since the Mother and her name are the same Truth and Principle, whenever the sadhak repeats her name, the Mother's presence remains with him. The difficult sadhana of transformation becomes very easy by doing nama-japa." Sri Ramkrishna Das goes on further to describe how the Mother found nama-japa to be indispensable for the transformation of the body. In 1959 the Mother herself said: "I have also come to realise that for this sadhana of the body, the mantra is essential . . . because only japa has a direct action on the body." The usefulness and effectiveness of nama-japa have been brought out by the author of this book in a lucid and straight forward manner. Part Two of this new edition features more questions and answers concerning the practice of Sri Aurobindo's Yoga as well as some anecdotes and experiences with Sri Ramkrishna Das that highlight his personality and his exceptional achievements in this yoga.
