True friendship exists when human beings share a love of goodness and truth. Two friends alone, like two legs on a table, offer a wobbly situation at best. But two friends anchored to a third, spiritual center form a rock-solid foundation to support everything that comes: hardship, suffering, exaltation, love. True friendship between two human beings exists only when there is a third Friend present: call this third friend God, or simply the Sacred.
~ from GIFTS OF THE SPIRIT by Kaufman and Zalinski
Time and space are the very music of God's harp, for each moment in time is empty of other moments, and each part of space is empty of other parts, so that we will not have to hear too much at once. That is why there are seasons.
