The main character in a seventies movie once remarked in existential exasperation, "Don't you realize what a thread we're all hanging by?" The metaphor may change, but the reality is the same. We live on something like an edge at all times, near a precipice, whether we realize it or not. The wise are those who know exactly what the situation is, and where they are, and possess an inner calm about it, along with an agility of balance and correction to deal with anything that may come. Agitation never helps. Fear can be self defeating. A peace deep in the spirit is the sole fount and fulcrum from which good things may arise and even endure, despite the age of the thread or the bare breadth of the edge.
