"Though methods play an important role in the early stage, the techniques should not be too mechanical, complex or restrictive. If we cling blindly to them, we shall eventually become bound by their limitations. Remember, you are expressing the techniques and not doing the techniques. If somebody attacks you, your response is not Technique No.1, Stance No. 2, Section 4, Paragraph 5. Instead 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 you something, you catch it. It's as simple as that - no fuss, no mess."
