A woodcutter was napping when his friend shook him and said, "Hey, wake up!"
"Why did you wake me up?" complained the woodcutter. "I dreamed I was a king, the ruler of a great kingdom and father to many children. I sat happily on my throne and administered justice to all my subjects. Why did you destroy my happy state?"
"But it was just a dream!" protested his friend. "What does it matter?"
"You fool!" said the woodcutter. "You understand nothing. Being a king is just as real, and not real, as my being a woodcutter."
So teaches the Vedanta.
