The body secret (secret in this instance means powerful inner method) hand gesture is a Feng Shui cure for aligning your body’s energy. You perform this gesture by flicking the middle and ring fingers out from the palm. The flicking motion is done nine times in a row. (Nine symbolizes completion and achievement.) Men should flick their left hand, women should flick their right hand. This flicking motion expels blocks and hindrances from your life and welcomes the positive benefits you desire.
