Haṭha yoga is a branch of yoga which uses physical techniques to try to preserve and channel the vital force or energy. The Sanskrit word हठ haṭha literally means "force", alluding to a system of physical techniques. Some haṭha yoga style techniques can be traced back at least to the 1st-century CE, in texts such as the Hindu Sanskrit epics and Buddhism's Pali canon. The oldest dated text so far found to describe haṭha yoga, the 11th-century Amṛtasiddhi, comes from a tantric Buddhist milieu. The oldest texts to use the terminology of hatha are also Vajrayana Buddhist. Hindu hatha yoga texts appear from the 11th century onwards.

Some of the early haṭha yoga texts (11th-13th c.) describe methods to raise and conserve bindu (vital force, that is, semen, and in women rajas – menstrual fluid). This was seen as the physical essence of life that was constantly dripping down from the head and being lost. Two early Haṭha yoga techniques sought to either physically reverse this process of dripping using gravity to trap the bindhu by inverted postures like viparītakaraṇī, or force bindu upwards through the central channel by directing the breath flow into the centre channel using mudras (yogic seals, not to be confused with hand mudras, which are gestures).
