" This is the pivotal point, maybe of this whole book. On the surface of our lives most of us build the hard shell. It is built to cover fear and insecurity and win approval and success. When you get down to the core of yourself, you find a different, more primeval country, and in it a deep yearning to care and connect. You could call this deep core of yourself the pleroma, or substrate. It is where your heart and soul reside. After her first daughter was born, a friend of mine, Catherine Bly Cox, told me, “I found I loved her more than evolution required.” I’ve always loved that observation because it points to that deeper layer. There are the things that drive us toward material pleasure, and there are evolutionary forces that drive us to reproduce and pass down our genes. These are the layers of life covered by economics and political science and evolutionary psychology. But those layers don’t explain Chartres Cathedral or “Ode to Joy”; they don’t explain Nelson Mandela in jail, Abraham Lincoln in the war room, or a mother holding her baby. They don’t explain the fierceness and fullness of love, as we all experience it. This is the layer we’re trying to reach in the wilderness. These are the springs that will propel us to our second mountain. "
