Svātmārāma

Yogi Swatmarama (Sanskrit: स्वात्माराम; IAST: svātmārāma) was a 15th and 16th century yogic sage in India. He is best known for compiling the yoga manual Hatha Pradipika or Light on Hatha Yoga. The manual describes the use of asana, pranayama, mudra, and shatkarma as practices for achieving Raja Yoga or samadhi. Very little is known about the actual Swatmarama, but the fourth line of the text attributes its lineage to the Nath Sampraday:
"Matsyendra, Goraksa, etc., knew Hatha Vidyā, and by their favour Yogī Swātmārāma also learnt it from them."
