Grand master Nanyang Huizhong was very grateful that his attendant served him for thirty years, so he meant to help him to get enlightened. One day, he called his attendant, "Attendant!"

Hearing master Huizhong's calling, he responded at once, "Grand master, what could I do for you?"

Master Huizhong said helplessly, "Nothing!"

After a while, master Huizhong called him again, "Attendant!"

Still he responded at once, "Grand master, what could I do for you?"

Again master Huizhong said helplessly, "Nothing!"

After many times of the same dialogue, master Huizhong changed, "Buddha! Buddha!"

The attendant was puzzled, and asked, "Grand master, who are you calling?"

Master Huizhong had to enlighten him plainly, "I am calling you."

The attendant was still puzzled, saying, "Grand master, I am a servant, not a Buddha!"

At this moment, master Huizhong sighed, "You may not blame me later that I have disappointed you. You are letting me down."

The attendant defended dreadfully, "Grand master! I will not let you down in any case, and you will not let me down, neither!"

Master Huizhong said, "Actually, you have disappointed me."
