The Gates of Paradise 
A soldier named Nobushige came to Hakuin, and asked: "Is there really a paradise 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 paradise," said Hakuin.
A Drop of Water 
A Zen master named Gisan asked a young student to bring him a pail of water to cool his bath.
The student brought the water and, after cooling the bath, threw on to the ground the little that was left over.
"You dunce!" the master scolded him. "Why didn't you give the rest of the water to the plants? What right have you to waste even a drop of water in this temple?"
The young student attained Zen in that instant. He changed his name to Tekisui, which means a drop of water.
