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.
