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.

No one can obtain felicity by pursuit. This explains why one of the elements of being happy is the feeling that a debt of gratitude is owed, a debt impossible to pay. Now, we do not owe gratitude to ourselves. To be conscious of gratitude is to acknowledge a gift.
