It is weight that gives meaning to weightlessness. (In the Japanese tea ceremony, light things are handled as though heavy, and heavy things as though light.)
What is sacred? The philosopher Friedrich Nietzsche said it was anything that you cannot or will not laugh at. But I have the exact opposite view. If I’m unable to crack a joke about what I regard as holy, then it’s not holy. For me, part of what makes an idea or person or object holy is its power to animate my sense of humor and put me in the mood to play.
