We have lost sight of the original harmony: If you could hear the sound that is produced by the sunflower as it keeps on turning its head toward the sun, the friction between the flower and air, and if you could hear the sound produced by the galaxies, you would hear the symphony of the spheres; and you would realize that this symphony is based upon a basic harmony, the harmony of the spheres.
~ by Proclus (c. 410-485)
