The spiritual journey is one that we must take "alone together," in the same way that a good marriage involves a dance between solitude and communion. The life of the spirit entails a continuous alternation between retreating into oneself and going out into the world: it's an inward-outward journey. There is a solitary part to it, but that solitude helps us to develop richer and more in-depth relationships with our friends, our children, our community, and the political world.
