Staying the night at Summit-Top Temple,--From The Selected Poems of Li Po--
you can reach out and touch the stars.
I venture no more than a low whisper,
afraid I'll wake the people of heaven.
Perhaps the universe is filled with intelligent creatures, but clearly we cannot be numbered among them. To imagine a sky filled with sentient beings, all of them angels and none of them demons, how much hubris and stupidity does that take?
Instead of trying to contact them, it is better by far to let them sleep.
