A boy while walking one day came across an old man building a great bridge across a deep valley. When the boy asked the old man why he was building the bridge the old man replied:
"Son I am the seeker of knowledge and on the other side of this valley is a vast land of knowledge."
The boy then asked:
"Wouldn't it be easier to climb into the valley then up to the land of knowledge?"
The old man answered:
"Many have tried that path never to return. It is a twisted path, one with many evils. I started this bridge knowing I would never see its end."
The boy questioned:
"So why did you start to build?"
The old man answered:
"I knew one day you would come along and continue the building for you too are a seeker of knowledge."
The old man died and the boy did continue to build. While building the boy realized that the bridge would never be completed but it was a bridge that must be built.
"Yes my son, I was that boy now an old man and yes you too are a seeker of knowledge. It will be you that takes my place when my time comes."
