Swami Satyananda said... "'Prana' means cosmic or vital energy which is inherent in the evolution of human life. 'Vidya' means knowledge. Just as you practice ajapa japa, yoga nidra or antar mouna, there is also a practical technique of prana vidya. By practicing for oneself every individual can awaken this prana and conduct it with a little higher voltage to a particular part of the body. The theory and techniques of prana vidya are ancient but I have revised and made them practical for the people of today. For this purpose I have printed the book Prana Vidya, which is now available at Bihar School of Yoga, Monghyr, Bihar, India, and I am presently preparing a more complete edition, Prana and Prana vidya which will be available very soon". - From http://www.yogamag.net/archives/1977/bfeb77/pv.shtml

About the Author:

Swami Satyananda is considered to be one of the major forces in bringing yoga to the West. He travelled the world tirelessly for over twenty years sharing the inspiration of yoga. During this time he wrote over 80 books on Yoga, Tantra and Spirituality. Swami Satyananda retired from public life in 1988 to work for mankind's upliftment in a more universal way. He moved to Rikhiapeeth, in a small village in Jharkhand in India, where he worked to support the local community and improve their quality of life.

After inspiring millions to live the divine life, Swami Satyananda took mahasamadhi at midnight on December 5th 2009 at Rikhiapeeth, leaving the present inspirers of the Satyananda Yoga tradition, Swami Niranjanananda and Swami Satyasangananda (popularly known as Swami Satsangi), to continue his work for humanity.
