When the energy does arise in your body these positions become automatic. We train our bodies to be loose enough to handle the energy when it does manifest. When this energy does arise, there is no mistaking it, it's not an intellectual experience. It overwhelms you and there will be very little of you left when it happens, and all that will be left is the essence of the light that is you. Most people when they have this experience, fight it. It's too overwhelming. It's too awesome. But let yourself go. Because sooner or later you're going to have to. It's like surfing the waves in the ocean, you have to go with them. You can't fight. If you fight you get beat up. So, know that you're dealing with all the energy of the universe, all the potential consciousness. Embrace that infinity. See yourself against that horizon that is never ending. Fearlessly, courageously, joyfully.
