Nothing is inherently and invincibly young except spirit. And spirit can enter a human being perhaps better in the quiet of old age and dwell there more undisturbed than in the turmoil of adventure...
~ George Santayana
A shah of Persia used to sit up at night for vigils and prayers. A friend who was visiting wondered at his long meditations after the whole day's work. "It is too much," he said, "you do not need so much prayer."
"Do not say so," was the answer. "You do not know. For at night I pursue God, and during the day God follows me."
