When you do not resonate with someone, the tendency is to
run away, to move in the opposite direction. 
The energy physically repels you. 
To run away is the human reaction—that, or to fight.  Both are protective measures of the ego.  There is another way.  Recognize ego at work.  Recognize that you are not the ego.  Rise above the clashing vibrations.  Stepping thus back into your true state of
consciousness as spirit, now see the one with whom you clash with
compassion.  Compassion immediately
brings you into alignment with your highest self which resonates with all
beings, for all beings are aspects of the highest self.  From this expanded state of awareness, you
can remain quite comfortably in the presence of any clashing vibrations, for
compassion is a mighty armor.
