A spiritual seeker was determined to fathom the meaning of life. He took to a long and arduous trip to the Himalaya to find his guru. He crested mountains and crossed rapid rivers. Finally after great efforts and privations he found the guru, who lived in a cave of rocks.
"Oh guru", he said with his last strength, "tell me, what is the meaning of life?"
"Life is like an onion", answered the guru.
"Life is like an onion??????????" called out the man.
"Never mind", the guru waved aside," then it is not like an onion."
