Milarepa had searched everywhere for enlightenment, but could find no answer - until one day, he saw an old man walking slowly down a mountain path, carrying a heavy sack.
Immediately, Milarepa sensed that this old man knew than secret he had been searching for.
"Old man, please tell me what you know, What is enlightenment?"
The old man smiled at him for a moment and swung the heavy burden off his shoulders, and stood straight.
"Yes I see!" cried Milarepa "My ever lasting gratitude. But please, one question more. What is after enlightenment?"
Smiling again, the old man picked up his sack once again.
Slung it over his shoulders, steadied his burden, and continued on his way.
