Hi Seedling,
The manual describes a transparent energy column of beautiful colors, running from the top of the head, to the bottom of the torso. That, fixes a visualization, and one's focus, in sort of a global self view of that area. That looks different to me, and is different than small universe. I know, that several people, including myself, have felt the relationship between this exercise and sm universe, turning that circle, moving up the back and down the front. I don't think this is wrong. I do think there is a difference between the energy moving that way, and the visualization given by Master Lin. If I do the visualization, I experience it as an overall view of that area, with the hands directing energy relative to where they are. Where you direct the energy, from your hands, and how you see that, is flexible. You might direct it to an area you feel blocked, you might be focused on the spine, which is a very important element to keep clear, regarding one's health, or, you might direct it to a central line or core of your being, or whatever, perhaps feeling that loop. This part can be intuitive, and it can change. Remember too, that the pathway of small universe, is how qi circulates. If your mind shifts there, it is easy to feel energy moving. Perhaps, that can be a draw to one's experience or focus. For the most part, I feel it as more a fixed view transformational state, or a more global view of one's body, as opposed to tracking around small universe. The constant state of that energy column, gives me that view. Energy , directed by the hands, moves up and down that column. That could be the outside, the center, the whole level, a slice/area relative to where the hand is, or the whole column lighting up.
love,
