“It is well known that Angels, having tens of thousands of years of contemplation to perfect the martial arts, are unparalleled masters of them. If you are to seek an angel master, be respectful to them. Defer to them on all matters, worldly and otherwise, for they are dogmatic and proud beings. Attend to their requests, clean their monasteries, and humble yourself in your actions and words.

Above all, do not spar with them, unless you want your arms torn from your sockets.”

Zao Xu, Horse Style Master, “49 Empty Palms”
