“Let us call this quality the Original Mind. This mind looked at the world more directly—not through words and received ideas. It was flexible and receptive to new information. Retaining a memory of this Original Mind, we cannot help but feel nostalgia for the intensity with which we used to experience the world. As the years pass, this intensity inevitably diminishes. We come to see the world through a screen of words and opinions; our prior experiences, layered over the present, color what we see. We no longer look at things as they are, noticing their details, or wonder why they exist. Our minds gradually tighten up. We become defensive about the world we now take for granted, and we become upset if our beliefs or assumptions are attacked.”
