Growing up, I always heard: “Do unto others as you would have them do unto you.” That was the Golden Rule.
I always had a problem with this, because I would love to have someone give me a million dollars, but I don’t have a million dollars to give away. I know. That’s a materialistic interpretation of spiritual advice, but that’s the way my mind worked when I was a kid.
As an adult, I learned this version (which I prefer): “That which is hateful to you, do not do to your fellow.”
Every major religion (and most “minor” ones, too) have a version of this “rule.” Kindness and respect are fundamental to human nature. Knowing that gives me hope for our future.
