“Material things have closed boundaries; they are not accessible, cannot be penetrated, by things outside themselves. But one’s existence as a spiritual being involves being and remaining oneself and at the same time admitting and transforming into oneself the reality of the world. No other material thing can be present in the space occupied by a house, a tree, or a fountain pen. But where there is mind, the totality of things has room; it is “possible that in a single being the comprehensiveness of the whole universe may dwell.”

“From the standpoint of daily life, however, there is one thing we do know: that we are here for the sake of each other – above all for those upon whose smile and well-being our own happiness depends, and also for the countless unknown souls with whose fate we are connected by a bond of sympathy. Many times a day I realize how much my own outer and inner life is built upon the labors of my fellow men, both living and dead, and how earnestly I must exert myself in order to give in return as much as I have received.”

“Lost opportunities, lost possibilities, feelings we can never get back. That’s part of what it means to be alive. But inside our heads – at least that’s where I imagine it – there’s a little room where we store those memories. A room like the stacks in this library. And to understand the workings of our own heart we have to keep on making new reference cards. We have to dust things off every once in awhile, let in fresh air, change the water in the flower vases. In other words, you’ll live forever in your own private library.”
