How is Kung Fu useful in attaining Enlightenment?
In forms of Enlightenment seeking (namely, most forms of Zen Bhuddism), the key is Meditation. The problem is, to meditate effectively (especially at the higher levels), an incredible amount of willpower, physical, mental and emotional strength are all needed to awaken yourself. The excercises and discipline that Kung Fu instills in a person are the greatest assets that one who wishes to be enlightned can possess. By increasing the physical, you prepare the mental. By developing the mental, you prepare yourself for the spiritual.
