A Zen master out for a walk with one of his students pointed out a fox chasing a rabbit.

“According to an ancient fable, the rabbit will get away from the fox,” the master said.

“Not so,” replied the student. “The fox is faster.”

“But the rabbit will elude him,” insisted the master.

“Why are you so certain?” asked the student.

“Because the fox is running for his dinner and the rabbit is running for his life,” answered the master.
