Stephen Hawkins in an interview spoke of his life goal to find the ultimate single equation that tied everything together. Einstein got close with his E=mc2. Certainly Hawkins was thinking about the relationship between Black Holes and stars and even atoms, molecules and cells but he may not have been completely ignoring metaphysics as well as physics. The recent movie about Hawkins seems to focus on his love of life and his relationship with his girl friend/wife. Maybe the singular formula was under his nose, maybe he was living it.
God is love.
If you think about it with the depth that Hawkins would, you would probably come to the conclusion that every commandment, every rule, every proverb of every religion or philosophy is a subset of that simple equation: God equals love and love equals God. Hence God loves us far more than any of us have ever loved our dearest one, and in turn we will love God. Since God loves us so dearly, each one of us, we are best to love each other also with all we have, getting us very close to the practice rule that says we should do to others as we would want them to do to us. This, commonly called the Golden Rule exists is all religions.
In everything do to others as you would have them do to you for this is the law and the prophets.
Gospel of Matthew
What is hateful to you, do not do to others. This is the entire; all the rest is commentary.
Hurt not others with that which pains yourself.
This is thge sum of duty; do nothing to others which if done to you would cause you pain.
No one of you is abeliever until they desire for their brother or sister that which they desire for themselves.
