Agni-Sara Dhauti

literally, "purging by cascading the fire." One of the six kriyas, agnisara dhauti consists of a rapid series of abdominal lifts or Uddhiyana Bandha. This technique builds great heat (tapas/agni) in the body while it strengthens the muscles which support the internal viscera. The heat comes from quickly burning lots of calories in the abdominal area.
