In our minds we are in our own universe. Our choices, environments, curcumstances have shaped our lives, feelings, emotions, perception of the world, and is completely unique to anything that has existed. However the
foundation of what we are is that spark of life, that "Light".
Another man, has that identical "Light" that you have, yet has been subject to totally different circumstances that put him in a different walk of life, state of mind, perception of the world, or rather, "universe" than you.
When you look at another man, you are looking at [you] in a parallel [universe]
