Good questions as always Tasha,
Regarding the "steps," there are two ways of looking at it:
One is as if it doesn't matter. At this point, Master Lin is teaching the 7-Steps with the feet staying on the ground, or raising and lowering the heels.
The other is to think of it as if you were doing it while walking in a circle. You just keep "walking" or alternating steps until you've completed your last "seven."
In regards to the hands helping your visualization, consider this...once your palms up hands come up to chest level, beyond that it starts bind up at the wrists or shoulders unless you adjust your hands.
Lift them and the energy up to chest-level and feel your hands energetically rise with the energy, continue rise to the next level, turn as you turn your physical hands and go back down.
Much Love,
Shawn
