The name comes from the Sanskrit words , "inverted" or "reversed", and , "a particular type of practice". The practice is described in the 13th century
Vivekamārtaṇḍa (verses 103–131) as a means of yogic withdrawal,
pratyahara. The pose was practised from the 17th century onwards in
hatha yoga under names such as Narakasana, Kapalasana and Viparitakaranasana; its purpose as a
mudra was to reverse the downflow and loss of the life-giving substance (
Bindu) through the use of
gravity. In the early Bindu Model of Hatha Yoga, as described in the
Hatha Yoga Pradipika and other texts, the vital fluid is held in the head but constantly drips down and is lost. Mudras were thought to block the central
sushumna nadi channel of the
subtle body and work to force the flow back up, or in the case of Viparita Karani actually to reverse the flow. A headstand is described and illustrated in
halftone as Viparita Karani in the 1905
Yogasopana Purvacatuska. File:Early Bindu Model of Hatha Yoga.svg|Early Bindu Model of
