Is not the “I” you think of as you the same within others?  It is true, others may think differently than you, and look different than you, and act differently, but take away the thoughts, the appearance, and the behaviors, and what is left?  Pure Being being a human being.  Look around you and you will see pure Being being a dog and a cat and a tree and a mountain and a bee and all that you see.  I AM.  This is what everything you see that has the slightest bit of awareness knows before all else and after all else.  So, when you are feeling separate, feeling different, feeling dissonant, remember I AM.  Connect at the heart with I AM and feel the softening.
