Emperor Wu asked the great teacher Bodhidharma, “What is the first principle of the holy teaching?”
Bodhidharma said, “Vast emptiness, nothing holy.”
“Then who are you, standing here in front of me?” asked the emperor.
“I don’t know,” said Bodhidharma.
The emperor didn’t understand.
Bodhidharma crossed the Yangtze River and went to the Kingdom of Wei. Later, the emperor raised this matter with his advisor, Duke Zhi. The advisor asked, “Your Majesty, do you know who that Indian sage was?”
“No, I don’t,” said the emperor. “That was Avalokitesvara, the Bodhisattva of Compassion, carrying the seal of the Buddha’s heart and mind.”
The emperor felt a sudden regret and said, “Send a messenger to call him back.”
Duke Zhi said, “Your Majesty, even if everyone in the kingdom went after him, he wouldn’t return.”
