"Walk the walk," we are often told by shallow thinkers. They presume this to be a metaphor for sincerity. They forget the footless. They neglect the legless. The rebuke the bottomless. The topless? "You can stay," says the horny fool, shallowly.
Sozan, a Chinese Zen master, was asked by a student: "What is the most valuable thing in the world?"
The master replied: "The head of a dead cat."
"Why is the head of a dead cat the most valuable thing in the world?" inquired the student.
Sozan replied: "Because no one can name its price."
This has been "Zen koans explained." A lover, not a friend.
