There is a story of a pilgrim who approached his teacher, asking him to reveal the nature of Heaven and Hell.
The teacher, without hesitation, told the pilgrim how gross and stupid he was for asking such a question.
The pilgrim was furious, his face became red and grotesquely distorted in rage, he raised his sword and prepared to strike the teacher dead.
The teacher remained calm and, without hesitation, said “That’s Hell.”
Whereupon the pilgrim was enlightened; his countenance immediately transformed and he bowed in deep heartfelt gratitude.
The teacher responded, “And that is Heaven.”
