Cheers Suki.
I had not considered these sorts of parallels. In some ways I prefer the metaphorical analogies like this to discussing purely physical shapes and movements. IMO trying to reduce complex human movement to undergraduate level physics and applied mathematics does not serve anyone well.
I've explored yoga a little this past year. Kundalini has always intrigued me, I see parallels with experiences and activities in my youth which I will not spell out (not for any arcane purpose ... they were in the early 1970s and not exactly legal but victimless, hopefully you get my drift). I'm doing some basic pranayama and meditation, but remain reluctant to delve too deep or in haste for fear of blowing some sort of spiritual gasket.
