Sitali - Tongue Hissing
Sitali pranayam is a well known practice. It refers to the sound caused when air is drawn or inhaled in through the protruding tongue that is curled into a tube. During the inhale phases, a cooling sensation is felt over the tongue and into the throat which refreshes and relaxes the mind and body. To perform Sitali, sit comfortably in any meditative posture. As you sit tall, place both palms on the knees in Gyan Mudra.
