A gesture or position, usually of the hands, that locks and guides energy flow and reflexes to the brain. By curling, crossing, stretching and touching the fingers and hands, we can talk to the body and mind as each area of the hand reflexes to a certain part of the mind or body.
In each mudra, exert enough pressure to feel the flow of energy through the "nadis" (psychic channels) up the arms but not enough to whiten fingertips.
