Uttanapadasana

Viparita Karani or legs up the wall pose is both an asana and a mudra in hatha yoga. In modern yoga as exercise, it is commonly a fully supported pose using a wall and sometimes a pile of blankets, where it is considered a restful practice. As a mudra it was practised using any preferred inversion, such as a headstand or shoulderstand. The purpose of the mudra was to reverse the downward flow of vital fluid being lost from the head, using gravity.
