I didn't write this one. (Gosh! I've quoted several "author unknown" tales here over the years). This is a good story though, so I hope you'll read on.
A huge, rough samurai once went to see a little monk, hoping to acquire the secrets of the universe.
"Monk," he said, in a voice accustomed to instant obedience. "teach me about heaven and hell."
The little monk looked up at the mighty warrior in silence. Then, after a moment, he said to the samurai with utter disdain, "Teach YOU about heaven and hell? I couldn't teach you about anything. You're dirty. You smell. Your blade is rusty. you're a disgrace, an embarrassment to the samurai class. Get out of my sight at once. I can't stand you!"
The samurai was furious. He began to shake all over from the anger that raced through him. A red flush spread over his face; he was speechless with rage. Quickly, menacingly, he pulled out his sword and raised it above his head, preparing to slay the monk.
"That's hell." said the little monk quietly.
The samurai was overwhelmed. Stunned. The compassion and surrender of this little man who had offered his life to give this teaching about hell! He slowly lowered his sword, filled with gratitude, and for reasons he could not explain his heart became suddenly peaceful.
"And that's heaven," said the monk softly.
