Svatmarama Yogendra

This Fourteenth Century "Lord of Yoga" (Yogendra) is the author of Hatha Yoga Pradipika , the oldest and most well-known of the surviving early manuscripts on Hatha Yoga. An earlier work (now lost) called simply Hatha Yoga, written by the Goraksha, was apparently available to Svatmarama, since scholars maintain that parts of it are incorporated into the Pradipika.
