"I am in darkness at the foot of a great mountain, searching under every stone for a precious jewel. The valley is covered in darkness, so I cannot find the jewel. Then I look up at the shining mountain peak. If the jewel is to be found, it must be at the top. I climb and climb, beginning an arduous journey that takes many years. At last I reach my journey's end. I stand bathed in the bright light. My eyesight is clear now, yet the jewel is nowhere to be found. I look upon the valley far below, where I began the climb many years ago. Only then do I realize that the jewel had always been within me, even then, and that the light had always shined. Only my eyes had been closed."
