In addition to learning Bassai Dai, I'm also learning Kanku Dai (Dai means greater by the way...). And that means "To view the sky". Which is really odd because, other than the very first move (where you do indeed look up, but without moving your head), it would be a really bad idea to do much looking at the sky: you're far better off looking at your opponents instead.

I'm not sure if there is any viewing of the sky at all in the viewing of the sky (lesser) kata, Kanku sho. Which is a much more senior kata, so we won't do it for a year or two yet!
