There are only two real mysteries in the universe. Mystery Number One: Why is there something and not nothing? Mystery Number Two: How come we are conscious, what is consciousness, how come we think? All the other mysteries are sub-mysteries, and depend on these first two. Slightly connected, a poem attributed to the Persian poet Hafez (1326 -1389): I wish I could show you, when you are lonely or in the darkness, the astonishing light of your own being.
