Sit in easy pose or in a chair with your spine straight. Apply Root Lock. Lift the chest high, chin in (i.e., Neck Lock). The hands are open with fingers straight. Begin by bringing your arms out to the sides, elbows bent, with the palms of the hands facing each other, about shoulder width apart. The hands are angled toward each other at a 60-degree angle. Now bring your hands towards each other at the center of your body, but do not let them touch. This movement is strong and sharp, something like a clap without touching the hands. As your hands move inward, tighten the sex organ and release it as the hands move back to the starting position.
For men the tightening is centered at the base of the sex organ, for women, the contraction includes the clitoris. This is not a Root Lock. The anus and navel point are not contracted with the sex organ.
Inhale in the starting position, exhale as you bring your hands in and squeeze.
