The name comes from the Sanskrit words , "intense stretch"; and ; , "posture" or "seat". The pose is a modern one, first seen in the 20th century. A pose with the name Uttānāsana is illustrated in the 19th century
Sritattvanidhi but it is quite different from the modern pose (lying on the back, with elbows touching the knees and the hands behind the neck). The modern pose is described in
Krishnamacharya's 1934
Yoga Makaranda, and in the works of his pupils,
B. K. S. Iyengar's 1966
Light on Yoga and
Pattabhi Jois's
Ashtanga (vinyasa) yoga.
Theos Bernard however illustrates the related pose "Padhahasthasana" (sic) in his 1944 report of his experience of
hatha yoga on the border of India and Tibet, suggesting the existence of a separate tradition. ==Description==
