Mudra gestures and body motions are kinetic expressions of the elemental forces in the psycho-physical body. The predominating force propels the mudras in a distinctive pattern. Earth energy makes the least movements. When the hands in a mudra pose remain in a single position for long periods is indicative that the earth element is prevailing.

The water element moves the hands and body in large, wide circles or wavy movements. Fire energy causes the hands and body to move with great force in straight movements and jerks. With body it appears as rocking. The elemental force of air is graceful and flowing. Its movement is a combination of curves and straight lines. Most nondescript motions of the hand and body belong to the Akasha (etheric) element.

In Yogic teachings, this subject of elements belongs to the field of Tattva Vidya (Science of the Elements). The directions in which the mudras flow likewise reveal the element in power. Upward movements indicate the influence of air; downward, that of earth; to the right or forward, fire; to the left or to the rear, water.

Why do mudras cause the hand, arms and body to move without any direction or control by the conscious mind? As we clasp our hands in mudra formation we cause energy to build up in the various psychic vortices in our hands, arms, and body. These vortices take on different polarities--positive, negative, and neutral. These emanating centers fluctuate in their polarity and strength in concordance with the currents generated.

The resultant magnetic fields of these vortices interact with one another causing the law of attraction and repulsion to take effect. This causes the fascinating motions of the mudras. However, it should be emphasized that even though the conscious mind does not produce the swaying and oscillation of the body appendages, it does have the power to cause the motions to cease. Therefore, there should not be any fear that mudra practices might cause an impairment in the conscious control of one's motor movement.
