Harbours

"Have you ever been at sea in a dense fog, when it seemed as if a tangible white darkness shut you in, and the great ship, tense and anxious, groped her way toward the shore with plummet and sounding-line, and you waited with beating heart for something to happen?
I was like that ship before my education began, only I was without compass or sounding-line, and had no way of knowing how near the harbour was."

Helen Keller
