We've changed classrooms for our sessions with Master Ni. Our new space is very small, even for Master Ni. We're all learning about controlling our sword tip and limiting our extension.
Master Ni said that when we practice on our own, the implication being in larger spaces, to practice extension right and left - up and down. He said that this was the meaning of the 'Chi' in 'Tai Chi', an extension to the limit.
This means then that 'Wu Chi' which precedes Tai Chi, means extension into the Void.
That's what I try to do.
Like subatomic particles - you never know what will emerge from the Nothing.
