The Most Valuable Thing In The World

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.”
