" a prayer that asked for quiet—for peace and for silence—and itself twisted and turned around the line strength in tranquility and tranquility in strength. I’d always understood “strength in tranquility” and taken “tranquility in strength” to mean that if one was strong, one could make the tranquility one needed. But now, twisting and turning through the corn maze, I began to see it differently, that “tranquility in strength” meant having the strength to keep one’s tranquility of mind, no matter what the world brought. It meant being tranquil—peaceful—even when one was strong, not bullying or picking fights. "
