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 kung fu? Hadn’t this water just now illustrated to me the principle of kung 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.
