Yogi Swatmarama, svātmārāma स्वात्माराम was a 15th and 16th century yogic sage in India. He is best known for compiling the Hatha Yoga Pradipika, which introduced the system of hatha yoga. Hatha yoga focuses on purification of the body as a path that leads to purification of the mind. As a result, prana or vital energy can flow and be handled. Gorakhnath, who was probably Swami Swatmarama's guru, belonged to a yoga sect called Nath pant. Nath sect came into existence to save the society from the misuse of tantraśāstra (from becoming the superstitious practice of ostensible black magic and sorcery).
