Re: What to do ?
In a perfect world, each practitioner would leave worldly thoughts in a little pile just off to the left when they bow upon entering a dojo. They might even, in a perfect world, forget to pick up that little pile of neuroses when they bow to leave the dojo. This is not yet a perfect world and so, as many people have said, we assess our part in the situation and make training choices that preserve our health and honor the sacred training space. Everyone who trains for any length of time will encounter some disagreeable and/or dangerous partner. How we respond to this situation is another key lesson in the way of harmony. Good luck and good judgement.
