The blue colour is everlastingly appointed by the Deity to be a source of delight; and whether seen perpetually over your head, or crystallised once in a thousand years into a single and incomparable stone, your acknowledgment of its beauty is equally natural, simple, and instantaneous.
It's very difficult to explain the effect the first blues record I heard had on me, except to say that I recognized it immediately. It was as if I were being reintroduced to something that I already knew, maybe from another, earlier life. For me there is something primitively soothing about this music, and it went straight to my nervous system, making me feel ten feet tall.
I held a blue flower in my hand, probably a wild aster, wondering what its name was, and then thought that human names for natural things are superfluous. Nature herself does not name them. The important thing is to know this flower, look at its color until the blueness becomes as real as a keynote of music.
