Nadabrahma Meditation

First stage: 30 minutes

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.

Second stage: 15 minutes
