A minister of the Dang Dynasty, despite his fame, power, and
wealth, considered himself of a humble and devout Buddhist. One
day, during a usual visit to his favourite Zen master, he asked the
master, "Your Reverence, what is egotism according to Buddhism?" In
a very condescending tone of voice, the master shot back, "What
kind of stupid question is that?" This unexpected response so
shocked the minister that he became sullen and angry. The Zen
master then smiled and said, "This, Your Excellency, is
egotism."
