I have been practicing the chakra sounds, but am not feeling the energy like you talk about in the video, perhaps there is something I am not doing correct?
Yes, that must be; if you are following along with the techniques step by step you will be able to feel the energy easily. Make sure you are relaxed, and focused in your body, and breathing deeply but gently in the belly area. Each breath must be taken from the belly area, and then on the exhalation let the sound ride on that out breath for as long as possible. Allowing the sound to vibrate in the chakra, throughout your whole body and expanding into your energy field, see this happening with your eyes closed.
