Sonic meditation is a little different than typical meditation. Sonic meditation is designed to give the necessary inertia to your Qi or life force (the force that beats your heart, blinks your eyes, grows your hair and nails). The idea is that you want as few obstacles, both mental and physical, as possible. The best way to do sonic meditation is laying down, prostrate, on your back. I recommend the use of a yoga mat and a pillow for comfort. The fewer kinks and crooks in your body, the better. The same with your thoughts. it works best when you completely allow the sonic meditation to flood your body with the frequencies and have no interfering thoughts.
