Ideally, friendships lead us into deeper communion with each other; those we love mirror the divine reality and so draw us closer to the One they reflect. In our humanness, however, we can forget that the friend is only a reflection of God and instead invest ultimate meaning in the relationship.
I believe we are part of the universal rhythmic process because we're all a part of nature--we are in it and of it. So like the ingoing and outgoing waves, we breathe in a similar way--we flow. Cosmic creativity and creative evolution are always going on. Everything is always singing.
