In this video, Kit Dale teaches his 'Becoming Formless Concept'. Kit is one of Australia's top jiu-jitsu competitors and a proponent of concept-based learning.
Kit got the inspiration for this particular concept from the famous Bruce Lee 'Be like Water' quote:
"Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way around or through it. If nothing within you stays rigid, outward things will disclose themselves. Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot, it becomes the teapot. Now, water can flow or it can crash. Be water, my friend"
