To focus on the positive does not mean to put your
head in the sand.  Sooner or later, as a
human, you must come up for air.  You
look around you and you see what you call evil. 
You know it, for it is in such dissonance with the heart and soul of
you.  Denying it does not make it go
away, but you need not condone it nor accept it.  There is a difference between allowing and
accepting.  Accepting says, “I live in a
world of duality, but perhaps by helping to spread ripples of love I can make a
difference.  And so, I allow these things
to unfold as they will, but I do not accept them as my path.  I give no power to any-thing but Love.  I see it, I recognize it, but I do not accept
this as my Truth.  I AM Love.”  With this mindset, and allowing others to
accept or reject their own truth, you find peace within the duality.
