The Happy Fish
Two Zen masters were walking beside a stream.
“How happily the fish are swimming in the stream,” observed one.
“You do not know the fish are swimming happily,” observed the other, thoroughly schooled in the notion of projection!
“You do not know that I do not know that the fish are swimming happily,” countered the first, apparently even more thoroughly schooled in the notion of projection!
