Superbrain Yoga® is a simple and effective technique to energize and recharge the brain. It is based on the principles of subtle energy and ear acupuncture. This powerful technique is explained in Master Choa Kok Sui's latest book Superbrain Yoga®.
Start by standing and holding your right earlobe with the thumb and index of your left hand, the thumb placed in front of the earlobe.
Then do the same thing with the right hand holding the left earlobe. The left arm is inside, under the right arm.
Slowly squat down while inhaling through the nose then slowly stand up up while exhaling through the mouth. The tongue is placed against the roof of the mouth. Do this 15 to 21 times every day, preferably early in the morning when you get up. Results can be expected in 2 to 4 weeks.
