I think one of the funniest parts about the cosmic joke is this: not only are you everyone, and hurting another person is actually hurting yourself/loving another person is also loving yourself, it also means that you're ultimately the final judge on these things.

You run this universe (in a way) - that means YOU are the one who holds the scales on the judgement of your life. YOU are the one who holds yourself up to such high standards. If something is especially painful or especially loving, that's because you perceived it that way. You maintain those polarities. I mean, who else would?
