"The true essence of things is invisible to the eyes. Our sensory organs love to lead us astray, and eyes are the most deceptive of all. We rely too heavily upon them. We believe that we see the world around us, and yet it is only the surface that we perceive. We must learn to divine the true nature of things, their substance, and the eyes are rather a hindrance than a help in that regard. They distract us. We love to be dazzled."
—Jan-Philipp Sendker, The Art of Hearing Heartbeats
