Thank you for sharing your experience happymillionaire,
Check out the Small Universe meditation in your course. It is a core component of the Spring Forest Qigong, whether you are just begining, or a master.
Doing some gentle stretches before your active exercises can help with the leaning to the side. Lean as much as is comfortable/safe for you - the video is just a guide.
In the Moving of Y&y, feel the energy from your palms interacting, strengthening, brightening, and clearing the energy of that Column of light in your torso.
Much Love,
Shawn
