Art is the expression of the self. The more complicated and restrictive a method is, the lesser the opportunity for the expression of oneีs original sense of freedom!
The techniques, though they play an important role in the early stage, should not be too restrictive, complex, or mechanical. If we cling to them we will become bound by their limitations. Remember, you are expressing the technique and not doing the technique.
When someone attacks you it is not technique number one (or is it technique number two, stance two, section four?) that you are doing, but the moment you become aware of his attacks you simply move in like sound and echo without any deliberation.
It is as though when I call you, you answer me or when I throw something to you, you catch it, that all.
