As with any hasta mudra, shunya mudra is particularly beneficial when meditating. It can be practiced while seated, prone, standing or even walking, as long as the body is relaxed and the posture is symmetrical. It is recommended that shunya mudra be practiced up to three times daily for five to 15 minutes each time, and should be discontinued when no longer needed for its health benefits.
In ancient texts, shunya mudra was cited as providing access to the realm of heaven by harnessing fire energy (represented by the thumb) and ether energy (represented by the middle finger).
Practicing shunya mudra is thought to provide relief from a range of hearing and balance issues, among them including:
- Motion sickness
- Ear disorders such as acute pain, hearing loss, and tinnitus
- Numbness anywhere in the body
In terms of Ayurvedic medicine, this mudra is beneficial to those with a dominant vata, which is the dosha (governing energy) associated with the nervous system and waste elimination.
