Viparitkari Mudra

Sun lies in the root of the navel, (solar nerve/solar plexus) and the moon (the lunar nerve) lies in mouth at the root of palate. The sun with its radiance pulls and consumes the nectar, which is secreted by the body and man is overpowered by death. To save that nectar, the sun is lifted up and the moon is lowered down, it is known as the Viparitkari Mudra. The method to do it is such that one should stabilize head on a small cushion on the ground in between palms of both the hands and raise feet upwards and stand straight on head. One who does this mudra every-day, the old age does not bother him.

Then move the front and lower part of the tongue and pull the tongue slowly with fingers and with a pair of iron tongs as well. By doing this the tongue gradually becomes longer and with the regular practice lengthen it to such an extent that it reaches between the eyebrows. The take the tip of the tongue into the center of the palate (the passage where the nasal tracts and throat meet). There is a place like a pit, which is called Kapal Kuhar. Enter the  tongue into this place upwards and look at the center of eyebrows. This is called the Khechari mudra. Those people who practice Khechari Mudra would never feel hunger, thirst, laziness and drowsiness. Diseases and old age never come to them. It prolongs life also.
