I do not understand electricity, but I can accept the laws by which it abides. I do not feel that way about the concept God. When I touch my mom's leg with my healing hand and watch her foot cramp up where the electricity is stifled, I call it electricity, not God. As we are each the center of the universe, we can choose to rationalize or to exist with the satisfaction that little can be known. Even that which we are led to believe is fact is most often mere speculation.
Human nature is inexplicable.
I don't need guilt or envy or false comfort. To me the only choice is to live as fully as I can while not transgressing others in ways I would not want to be transgressed. It's all a roller-coaster to nowhere anyway. But that doesn't mean I'm going to cover my bases and try to convince myself of or profess something the core of my Self ultimately finds absolutely unacceptable. There aren't many reasons to fear death that really hold up under scrutiny, as far as I'm concerned.
