When Billy-Bob Gautama was a young man, he met a great teacher, and soon the two of them were engaged in deep conversation about the Manifold Path and the Four Virtues. As they spoke, the teacher poured beer into Billy-Bob’s glass. When the glass was full, he kept pouring, and soon the beer spilled onto the table. “Now wait,” said Billy-Bob. “That glass won’t hold any more.” “That is right,” said the teacher. “And if you don’t empty your mind, no new wisdom can enter it.” “I get that,” said Billy-Bob. “But if you don’t quit spilling my beer, I’m going to kick your ass.” Thus the teacher was Enlightened.
