Uh-oh, I guess I better stop practicing MA because I don’t want to go to hell.
This is my favorite part:
[i]Avoid an class which teaches breathing exercises;
Avoid any class which teaches “meditation”;
Avoid any class which teaches “Eastern philosophy”. American 5th Dan Master Instructor Bob Miller initiates boys as young as 5-year-old into his own free-style version of Hapkido, which is a Korean Martial Art similar to “soft”-style Karate. He has stated: “While I teach them on a physical level, I throw philosophy at them” [32];
Avoid any class which claims to utilize “latent power”, for example, by encouraging students to develop their “inner potential” or “spiritual potential”;
Avoid any class which claims to give specific training to achieve “calmness of mind” or “equanimity”, which is usually a euphemism for training in the cultivation of occult passivity;
Avoid any class which claims to teach a particular school, system, or type of “Martial Art”, such as Wu Shu, Karate, Ju-jitsu, Spirit Combat, Feng-sao, or anything ending in -do (e.g. Judo, Yudo, Iaido, Aikido, etc.), as all refer to “Martial Arts”;
Avoid any class in which the leaders are secretive and reluctant to discuss special techniques, reserving such discussions only for advanced grades; [/i]
