Note: I don't do stories, not here anyway. But the person who asked me to tell a story was sincere; so I told this person the following story that I had heard when I was a kid.
A young man was eager to find out all the answers about life, so he was reading as many books as he could find on the topic---life. One day he came across a book that was very difficult to understand. So he needed some smart person to explain the text to him. He had heard of a monk in a nearby temple who was wise, so he took the book to the monk hoping he would be able to help him.
To his surprise, when the young man pointed to the text and asked the monk to explain its meaning, the monk humbly said, �young man, I am illiterate, so I wouldn�t be able to tell you what it means. But if you read it to me, maybe I could explain it to you.� The young man was disappointed, so he said, �How could you help me if you cannot even read? I need someone who is smart.�
With his finger, the monk pointed at the crescent moon outside the window. He said, �young man, over there is the moon, look�. The man look to the direction of the monk�s finger and saw the beautiful moon. The monk continued, �You don�t need my finger to find where the moon is. But it helps when I pointed to it with my finger.�
The moral of the story is that reality (the truth) and the symbols of it (eg., writings) are two different things. That is, you can "know" the truth without able to express it in writing. But a piece of writing can only point to the truth, it is not the truth itself.
