Hatha Yoga Pradipika (Light on Hatha Yoga) includes the original Sanskrit text compiled by Maharishi Swatmarama with a translation and thorough commentary in English by Swami Satyananda and Swami Muktibodhananda. This text includes the entire science of Hatha Yoga (asana, pranayama, shatkarma, mudra and bandha) as it was conceived and practised not only for health and fitness but for awakening the vital energies: pranas, chakras and kundalini shakti. It points out that Hatha Yoga is not just a physical practice but a process of cellular transformation from gross to subtle to divine.
