such diversity is born: violet, indigo, blue, green, yellow, orange and red? What better than light represents this passage from unity to diversity and diversity to unity? And now, look at these colours and try to see where the red ends and the orange begins. Show me where they separate, where the border lies between the two. You won't find it, because it isn't there. And the example of light is particularly interesting, since light is the very substance of the universe."
