How does a Shaolin master defend against black magic? If you know Chinese, especially Cantonese, you may have come across this expression: if your luck is good, evil cannot come near you. “Good luck” in Chinese is “hao yun qi”, or “ho wan hei” in Cantonese, which is word for word “good-circulation-energy”. A Shaolkin master has not only good circulation of energy, but also a powerful, trained mind. The good circulation of energy around your body acts like electricity, into which evil forces may not penetrate. Low level spirits, like ghosts, are actually scared of the radiant energy of a vibrant person. But that does not mean a Shaolin master would go about fighting black magicians. Shaolin teachings also place much importance on another principle: live and let live.
