Re: consumed by the opponent
I think all emotions should be dealt with. Happy or sad. Angery or cheery. You need to deal with all your emotions. That being said the way you choose to deal with it is the ending factor of this matter. I might choose to not deal with it. In essence I'm dealing with my fealing by leaving it alone... Obviously this is the course you take when you happy go lucky... When you angry you might choose to deal with it on the mat by gently throwing your classmates around... or you might deal with it through misougi <Spelling> or you might talk with whomever about what your angry with. It all depends on what, when where, how why.... all the key factors.
So in other words you need to control your feelings not let them control you.
