Khechari Mudra, a yoga technique and type of hand gesture, is commonly practiced in Hinduism and Yoga, and is also referred to as the "tongue-locking" mudra.
The technique involves skillfully manipulating the tongue to reach the soft palate at the roof of the mouth and then closing the lips to seal the nasal passage. The ultimate goal is to control the flow of prana, or life force, in the body and awaken spiritual awareness.
The practice of Khechari Mudra is known to yield numerous physical and mental benefits, including heightened concentration and meditation, improved digestion, reduced stress and anxiety, better sleep, and increased energy levels. However, it's important to note that Khechari Mudra should only be attempted under the guidance of a qualified and experienced yoga teacher. This technique is not suitable for everyone, and incorrect performance can be hazardous.
In some cases, Khechari Mudra may involve the surgical cutting of the frenulum, which is the piece of skin connecting the tongue to the floor of the mouth. This procedure should only be carried out under the supervision of a qualified medical professional, after thorough consideration of the potential risks and benefits.
