What to do when you find that you have a different belief system from one with whom you share space?  Share love.  See yourselves involved in the ever-ongoing dance of life.  This includes all opposites.  Forget right and wrong, mine and yours, and simply dance.  When you reconcile differences with love, the result is wholeness.  Everything the other displays is within you, for both of you are souls with limitless potential.  You simply choose to express one particular aspect of being and the other expresses another.  As long as neither of you do harm, celebrate your uniqueness.  You do not have to agree.  Simply be.  Find what lies above all apparent differences:  pure Being.  Love, and dance as one.
