A soldier named Nobushige came to the famous Zen master Hakuin, and asked: "Is there really such a thing as heaven and a hell?"

"Who are you?" inquired Hakuin.

"I am a samurai," the warrior replied.

"You, a soldier!" exclaimed Hakuin. "What kind of ruler would have you as his guard? Your face looks like that of a beggar."

Nobushige became so angry that he began to draw his sword, but Hakuin continued: "So you have a sword! Your weapon is probably much too dull to cut off my head."

As Nobushige drew his sword Hakuin remarked: "Here open the gates of hell!"

At these words the samurai, perceiving the master's discipline, sheathed his sword and bowed.

"Here open the gates of heaven," said Hakuin.
