This exercise is said to give your nervous system great strength. You have to qualify yourself to be a Sensory Human.
Posture: Sit straight in a cross-legged position.
Mudra: Cup the hands slightly and clap them in front of the heart at the rate of one clap per second. Your hands must create a sound. Elbows are relaxed down.
Eyes: Eyes are closed.
Breath: Breathe in rhythm with the motion through pursed lips, inhaling as the hands are spread, and exhaling as you clap the hands together.
Time: Continue for 11 or 31 minutes.
During the last 2 minutes grip the hands together in front of the heart, tightening the hands as much as you can so that the energy begins penetrating your body. Breathe long and deep to control the energy.
To end: Inhale deeply, hold, and tighten your grip and your spine so that the energy goes through the entire nervous system. Exhale. Repeat 2 more times. Relax.
The success of the exercise depends on how tightly you tighten your hands during the last 2 minutes. If you feel dizzy following the exercise, drink some water immediately.
