Bruce Lee (November 27, 1940-July 20,193), the legendary martial artist, actor/film maker, and philosopher lived a life based on adaptability.
In the book Artist of Life, he is quoted as having written:
"When my acute self-consciousness grew to what the psychologists refer to as the “double-bind” type, my instructor would again approach me and say, “Loong, preserve yourself by following the natural bends of things and don’t interfere. Remember never to assert yourself against nature; never be in frontal opposition to any problems, but control it by swinging with it. Don’t practice this week: Go home and think about it...After spending many hours meditating and practicing, I gave up and went sailing alone in a junk. On the sea I thought of all my past training and got mad at myself and punched the water! Right then — at that moment — a thought suddenly struck me; was not this water the very essence of gung fu? Hadn’t this water just now illustrated to me the principle of gung fu? I struck it but it did not suffer hurt. Again I struck it with all of my might — yet it was not wounded! I then tried to grasp a handful of it but this proved impossible. This water, the softest substance in the world, which could be contained in the smallest jar, only seemed weak. In reality, it could penetrate the hardest substance in the world. That was it! I wanted to be like the nature of water.
Suddenly a bird flew by and cast its reflection on the water. Right then I was absorbing myself with the lesson of the water, another mystic sense of hidden meaning revealed itself to me; should not the thoughts and emotions I had when in front of an opponent pass like the reflection of the birds flying over the water? This was exactly what Professor Yip meant by being detached — not being without emotion or feeling, but being one in whom feeling was not sticky or blocked. Therefore in order to control myself I must first accept myself by going with and not against my nature.”
The thought is also expressed during an episode of the TV series Longstreet where Bruce Lee is filmed stating:
"Don't get set into one form, adapt it and build your own, and let it grow, be like water. Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup; You put water into a bottle 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."
It is a timeless idea, as man must constantly adapt to surroundings. Anything, including what a man creates, if it is to be enduring, must be created with the same adaptability.
