Professor Cheng was once asked, “What is the most important reason to study Tai Chi Chuan?”
“The most important reason is that when you finally reach the place where you understand what life is about, you’ll have some health to enjoy it,” was his answer.
More than self-defense, more even than its health benefit, he taught Tai Chi Chuan as a Tao, a “way of life”.
