In this final clip about the Biu Jee Garn Sau, we see the relationship of the two arms working together. Sigung emphasized that the motion was a scissoring up and down of the arms as the body turns from the centre. The transitioning between up to down and visa versa on each arm reminded me of twisting a piece of ribbon at each end to create the spiral shape/vortex force that occurs throughout Biu Jee. I love the demonstration that Sigung does at the end. The shapes are perfect and the smile that comes across his face gives a glimpse of the beautiful person that he was.
