I put back my head, looking up at the deep black sky swimming with hot stars. If you knew they were really balls of flaming gas, you could imagine them as Van Gogh saw them, without difficulty . . . and looking into that illuminated void, you understood why people have always looked up into the sky when talking to God. You need to feel the immensity of something very much bigger than yourself, and there it is – immeasurably vast, and always near at hand. Covering you.
