"Ingram did an echocardiogram. Eric was on his back, with a skewed view of the monitor, and wasn't sure whether he was watching a computerized mapping of his heart or a picture of the thing itself. It throbbed forcefully on-screen. The image was only a foot away but the heart assumed another context, one of distance and immensity, beating in the blood plum raptures of a galaxy in formation. What mystery he glimpsed in this functional muscle. He felt the passion of the body, its adaptive drive over geological time, the poetry and chemistry of its origins in the dust of old exploding stars. How dwarfed he felt by his own heart. There it was and it awed him, to see his life beneath his breastbone in image-forming units, hammering on outside him."
