Form is simple. Go into the emptiness and simply and easily move your body as Chunyi Lin demonstrates on the Tape. Initially you can follow along with eyes open close them if they want.
While you may not have everything perfect, loving faster than Chunyi Lin, not sure about the breathing it's more benefical to notice the flow of your body, this allows you to notice the energy flowing through your body and if any minor adjustment is required to the movement, you'll notice it when you review the course.
As for questions ask away. We all have our own experiences with it.
