One day, a student went to the mountain to meet the knowledgeable person to ask them a question. After a long time walking and pondering, they finally reached the top of the mountain, where they found the knowledgeable person hiding behind a curtain.
The student was uncertain and fearful, but went on and asked the question. Then waited for an answer. After a while, instead of answering, the knowledgeable person sneaked a branch out of the curtain and slapped the student.
Intimidated, the student asked: "why, knowledgeable person, did you slap me?"
The knowledgeable person did not answer him.
So the student walked away, wondering what they did wrong.
Unable to find answers to their questions, the student gave up and started to work at their parent's shop.
On the other hand, the knowledgeable person died alone on the mountain and nobody cared, because nobody cares about a person that does not want to build a better community, even if they know everything.
