In reply to:
If my memory does not fail me it is mentioned in the "David Bowie and the occult" article that Bowie started doing that move on stage when he was singing the "From Kether to Malkuth" line during the Station to Station tour.So I guess it has some symbolic mystic meaning, representing the cabalistic tree of life or something...
Yes, I think it's supposed to symbolise the spiritual transition from Kether at the top of the Tree to Malkuth at the bottom (or maybe the other way around, I'm not too sure), which is what Qabalism is about.
Did the world just explode?
