Hi Rockchuk,
Look at the visualization of energy moving, as a means to reaching emptiness. You are focusing your mind on something, giving 'it', something productive to do that benefits you. Over an ongoing practice, this focus on moving energy, is somewhat the same as a mantra. It becomes a singular repeating point of focus. In longer or deeper focus, you can lapse in and out of self conscious focus, and slip into deeper states, perhaps emptiness, or at a minimum, moving closer to that. Regardless, you are aware of the shift, as you become self conscious again, and rejoin your focus and self awareness. One is the means to reach the other, as opposed to looking at it as a choice between two different things. You can be relaxing, innertubing down the river, doze off, with no awareness of the river, and come to again, finding that you continue to flow with the current and direction of the water.
love,
gallen
