Before he became a hermit. Zarathud was a young Priest, and took great delight in making fools of his opponents, in front of his followers.
One day Zarathud took his students to a pleasant pasture and there he confronted The Sacred Chao while She was contentedly grazing.
“Tell me you dumb beast,” demanded the Priest in his commanding voice, “why don’t you do something worthwhile? What is your Purpose in Life, anyway?”
Munching the tasty grass. The Sacred Chao replied “MU”. (The Chinese ideogram for NO-THING.)
Upon hearing this, absolutely nobody was enlightened.
Primarily because nobody understood Chinese.
