But these young people have such an intelligent, knowledgeable surface, and then the crust suddenly breaks and you look down into depths of confusion you didn't know existed.”

“He's like a lake. You assume it has great depths, pure undisturbed undiscoverable depths. You assume depths must be there because the surface is so flat--pretty and flat and utterly unrevealing.

If you try to learn this knowledge without a teacher you will go astray and affairs will become so confusing to you that you will be more astray than Toma*, the physician.*توما الحكيم”

“It is like looking down from the cliffs of Moher into the depths. Many go down into the depths and never come up. Only the trained diver can go down into those depths and explore them and come to the surface again.”

“Stir not murky waters if you know not the depth or the creatures that dwell beneath the surface.”
