Zen

Zen
A nun asked a Zen patriarch for help in understanding the Mahanirvana Sutra. The master answered that he could not read, but if the nun would read it aloud for him, he would do his best to help her.
The nun then asked, "If you can't even read the words, how can you understand the truth behind them?"
"Truth and words are unrelated. Truth can be compared to the moon," answered Hui Neng, pointing to the moon with his finger, "And words can be compared to a finger. I can use my finger to point out the moon, but my finger is not the moon, and you don't need my finger in order to be able to see the moon".
