DRAIN WAVE VIBRATION is so SIMPLE that it can be done by anyone of any age in just about any condition. However, like any exercise, you should not push yourself beyond your limits, and you should discuss your plans with your physician if you are concerned at all about your physical readiness to participate. Here are some precautions to keep in mind:

If you are older or very weak

You first need to stimulate your physical energy. The center of that energy is located in your lower abdomen, about two inches below your navel. Before beginning the Full-Body Brain Wave Vibration exercise, warm up with the Abdominal Vibration exercise on page 138. When YOU begin full-body practice, start with only very slight vibratory movements. It you stand during practice, make sure your feet are planted solidly on the ground and that your knees arc slightly bent. If necessary, assume a seated or lying posture. You can also practice while balancing against a stable object, such as a wall or a sturdy piece of furniture.
