Re: The Empty Body
Words. Literally saying the same words? I doubt many do except those who copy. Conceptually though I bet most did and do but do you hear them is the question.
Empty mind: empty of what? Thoughts, confusions, etc.etc. Therefor no attention on such things.
Empty body: empty of what? feelings, tensions, etc. etc. Therefor no attention on such things.
All experienced martial artists mention these things as essential to energy flow and may use such terms as calm body, relaxed body, weight underside body, etc. etc etc.
Very simple really. Not so simple to achieve.
