A brilliant interview was given by Dr. Sung Won Lee, secretary of the International Brain Education Association, about Dahn Yoga and Brain Wave Vibration for Sonoranliving.com. I thought he gave a good introduction for the general public in the video. The text on the website offered some useful suggestions for Dahn Yoga exercises you can do at your desk, so I copied them here for your benefit:
1. Breathing with the Brain. As you repeat this exercise several times, you can experience a sensation as though someone is pressing down from the crown of your head. Sitting comfortably in a chair, straighten your spine and relax your shoulders. Take several deep breaths as you relax body and mind. Breathe in as you focus your awareness on the point [at the crown of your head]. As you breathe in, imagine energy entering with the point open wide. Breathe out through your mouth; imagine the stale energy stagnant in your head leaving your body with your breath. As you inhale, imagine energy entering and washing your brain. As you exhale, imagine stagnant energy leaving through your mouth. Repeat this inhale-and-exhale cycle for at least three minutes.
2. Spread Arms to Open Chest. The longer you sit at your desk, the more your shoulders will start to feel stiff and your head will feel hot. This means that energy, unable to circulate through the whole body, is stagnating in the head. With this exercise, you will feel energy passing through your chest and spreading evenly to your whole body, so that new vitality will fill your brain. Stand comfortably with your feet shoulder width apart. Extend your arms to the front with your palms facing each other. Spread your arms apart as far as possible to open your chest fully. Maintain this posture as you focus your awareness on places where you feel a pulling sensation. Return to your original position. Inhale as you spread your arms, pulling them toward your back, and exhale as you bring them together toward your front. Repeat this at least six times.
3. Neck Rotations. Neck and shoulder stiffness hinders the upward flow of blood and oxygen to the brain, keeping you from having a clear head. This exercise will refresh your neck and spine, and stimulate your central nervous system by helping your flow of spinal fluid. Do sitting or standing. Keep your spine straight and relax your shoulders. When the exercise is done in a standing position, it’s good to have the feet shoulder width apart. Hold your right shoulder with your left hand and turn your head to the left as far as possible. With your head turned as far as possible, maintain this posture and focus your awareness on places where you feel a pull. As you exhale, return to your original position. Now do it in the opposite direction. Hold your left shoulder with your right hand and turn your head to the right as far as possible. Repeat this exercise at least twice. Inhale as you start the movement, hold your breath for a short time while you hold the posture, and exhale as you return to the starting position.
The article also explains that one of the principles of Brain Wave Vibration is that in changing our brain waves, we are changing them towards this positive attitude that we all aspire to. We are improving our brain function by pushing stress out and good thoughts in, and while that seems simplistic, it is actually quite profound and effective.
