Shankh Mudra of shell
Encircle the your thumb with the four fingers of your right hand. At the same time, touch the right thumb to the extended middle finger of your left hand. Together, the two hands look like a conch shell. Hold your hands in front of your sternum. Do this as often and as long as you want. Or use it three times daily for 15 minutes as a course of treatment. When you want to practice this mudra, you can first sing “OM” several times. Then listen within yourself, to the silence, for several minutes afterward. This mudra is used during rituals in many Hindu temples. There, the conch horn is blown in the morning to announce the opening of the temple doors. The same applies to our inner temple, in which the divine light shines—it should also be opened.
The Shell or Shankh Mudra drives away every kind of problem in the throat. If you practice it regularly, especially if you sing “OM” as you do it, you can improve your voice. It also has a very calming effect and leads to collection in silence.
