"We are a way for the cosmos to know itself."

"The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries."

"And you are made of a hundred trillion cells. We are, each of us, a multitude."
