Mudras

Yoga Mudras are understood as a healing modality.
The Sanskrit word Mudra translates as gesture, mark, or seal.
Mudras are generally hand positions, though they can also be shapes we make with the whole body or with a specific area of the body.
Mudras are said to affect the movement of Prana, which is life force energy.
In Western terms, mudras may stimulate the nervous system, creating beneficial shifts in both our physical and mental state.
Mudras may also affect our energy body and emotions.
The best way to understand the effects of mudras is to use them in your practice and discover, experientially, how they make you feel.
