This is an old Tibetan technique of humming, which creates a healing vibration throughout the body, and a hand movement which centers the energy at the navel.&nbsp; Nadabrahma meditation lasts for one hour and has three stages. It can be done at any time of day, alone or with others, but have an empty stomach and remain inactive for at least 15 minutes afterwards.&nbsp; First stage: 30 minutes&nbsp; Sit in a relaxed position with eyes closed and lips together humming loudly enough to be heard by others and create a vibration throughout your body. You can visualize a hollow tube or an empty vessel, filled only with the vibrations of the humming. A point will come when the humming continues by itself and you become the listener. There is no special breathing and you can alter the pitch or move your body smoothly and slowly if you feel like it.&nbsp; Second stage: 15 minutes The second stage is divided into two 7 1/2 minute sections. For the first half, move the hands, palms up, in an outward circular motion. Starting at the navel, both hands move forwards and then divide to make two large circles mirroring each other left and right. The movements should be so slow that at times there will appear to be no movement at all. Feel that you are giving energy outwards to the universe. After 71/2 minutes turn the hands, palms down, and start moving them in the opposite direction. Now the hands will come together towards the navel and divide outwards to the sides of the body. Feel that you are taking energy in. As in the first stage, don't inhibit any soft, slow movements of the rest of your body. Third stage: 15 minutes Sit or lie absolutely quiet and still. &nbsp;
