If you believe you are only a body, you must then agree that your entire life, everything you know and have experienced is only the result of electricity and chemicals. If what I know and feel, the love I have known and the pain I am learning from is somehow only chemical and electrical I will accept it but I can only look at it reasonably as a complicated gift.
I’m uncertain enough of the universe to acknowledge that I am unlikely the center of it. Where do I look to acknowledge the gift of the love I have known and the pain I am learning from?
If there are instances where it seemed an event unlikely to happen somehow did, you could cock your ear to the Universe and ask if someone said “Hello”.
