“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.” - Bruce Lee
These are beautiful words on hand-to-hand combat by a man who spoke truths about the martial arts that no one before him truly understood. But what does he really mean with these words, and how do we implement them.
“When the opponent expands, I contract. When he contracts, I expand. And, when there is an opportunity, I do not hit - it hits all by itself.” - Bruce Lee
This quote provides some more insight on what is being conveyed with his philosophies on fighting. When the opponent expands, attacks, moves forward, I contract, block, slip, evade. Every action has a reaction, and when an opening presents itself, our muscle conditioning should make us hit all on its own without thought.
We all have differing ranges, depending on how long our limbs are or how we throw our shots.
If one can understand all three then you can easily draw your opponent into dead space, the area where punches are missed, and let your weapons 'hit all by itself'.
