Someone asked Zhaozhou, “Does a dog have Buddha nature or not?”
“Yes,” replied Zhaozhou,
“Then why did it jump into that bag of fur?”
“It knew what it was doing and that’s why it dogged.”

“All beings have buddha nature. Why doesn’t a dog have it?”
“Because it’s beginning to awaken in the world of ignorance.”
