You mean stopped, not mastered, don't you? 
Ahhh... ok you were talking to me.
Good to know.
I meant mastered like oriental self control, although that has been considered a sin by Pope Benedict XVI.
Thank You.
The problem here, you see, are Martial Arts and Oriental "Self Control".
Self Control is always a problem when applied to Religion and Oriental Self Control (Yoga, Martial Arts, Buddhism, etc...) is considered magic by the Vatican.
Magic is a sin.
Thank You.
