Haṭha yoga is a branch of yoga. The Sanskrit word हठ haṭha literally means "force" and thus alludes to a system of physical techniques. In India, haṭha yoga is associated in popular tradition with the Yogis of the Natha Sampradaya through its traditional founder Matsyendranath, who is celebrated as a saint in both Hindu and Buddhist tantric and haṭha yoga schools. Almost all hathayogic texts belong to the Nath siddhas, and the important ones are credited to Matsyendranath's disciple, Gorakhnath or Gorakshanath. According to the Dattatreya Yoga Śastra, there are two forms of haṭha yoga: one practiced by Yajñavalkya consisting of the eight limbs of yoga, and another practiced by Kapila consisting of eight mudras.
