These books are about the Himalayan Sage - Swami Rama. The most admirable and the unique quality about this sage is that he had put himself under the Scientific Experiments of American Scientists and clearly proved that the control of the Body, Healing of the dreadful diseases are possible by means of Yoga sciences. (While the same is not possible through the normal medicines)
The problem we face today is that We never realise the hidden potential of Our ancient tradition. The Vedas, Mantras, Yoga are the jewels of the Eastern countries. The East is rich in sprituality but lack science and the west the vice versa. As the words of Swamiji, the West and East should be bridged. So, that a lot of Useful thing could be achieved for a prosperous future.
