Mayu Fanning (GK)

KOAN:

Master Mayu Baoche was fanning himself. A student approached and said, “Teacher, the nature of wind is permanent, and there is no place it does not reach. Why, then, do you fan yourself?”
“Although you understand that the nature of the wind is permanent,” replied Mayu, “you do not understand the meaning of its reaching everywhere.”
“What is the meaning of its reaching everywhere?” asked the student again.
The teacher just kept fanning himself.
