Aside from the invocation of energies, of communion with divine forces, mudras have the power to purify the etheric nervous system and the energy-centers to be found in the etheric body.

It cleanses all obstructions and congestion that prevents the free flow of pranic and kundalinic forces through the nadis and the chakras. The etheric or "vital" body as it is sometimes called, is the blueprint and the power house of the physical body.

When the interface between these two bodies are affected adversely in some way because of the toxins that we generate through negative thoughts and emotions, and the degenerative substances found in the food that we consume, and likewise un-cleared karma and trauma, then the physical body would suffer as a consequence. Ill health and a poor immunity system would result. Substances would crystallize in the tissues and the fluid-networks in the body, giving rise to muscular pain, impaired functioning of the organs, and the ossification of blood vessels which technically is the diseased condition referred to as arteriosclerosis. Certain mudras may heal these maladies.

While performing mudras, it is not unusual for the hands, arms, body and head to move on their own accord. The movement patterns that the mudras generate during practice are countless.
