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".*

Upon hearing this, absolutely nobody was
enlightened. Primarily because nobody could
understand Chinese.

* "MU" is the Chinese ideogram for NO-THING.
