[Don't confuse the pointing finger with the moon]
The Zen teacher's dog loved his evening romp with his master. The dog would bound ahead to fetch a stick, then run back, wag his tail, and wait for the next game.
On this particular evening, the teacher invited one of his brightest students to join him - a boy so intelligent that he became troubled by the contradictions in Buddhist doctrine.
"You must understand," said the teacher, "that words are only guideposts. Never let the words or symbols get in the way of truth. Here, I'll show you."
With that the teacher called his happy dog. "Fetch me the moon," he said to his dog and pointed to the full moon.
"Where is my dog looking?" asked the teacher of the bright pupil.
"He's looking at your finger."
"Exactly. Don't be like my dog. Don't confuse the pointing finger with the thing that is being pointed at. "All our Buddhist words are only guideposts. Everyman fights his way through other men's words to find his own truth."
