Chapter 6, Part 11A - Chuang Tzu

Master Sang-hu, Meng-tzu Fan, and Master Chin-chang, three friends, said to each other, "Who can join with others without joining with others? Who can do with others without doing with others? Who can climb up to heaven and wander in the mists, roam the infinite, and forget life forever and forever?" The three men looked at each other and smiled. There was no disagreement in their hearts and so they became friends.

After some time had passed without event, Master Sang-hu died. He had not yet been buried when Confucius, hearing of his death, sent Tzu-kung to assist at the funeral. When Tzu-kung arrived, he found one of the dead man's friends weaving frames for silkworms, while the other strummed a lute. Joining their voices, they sang this song:

Ah, Sang-hu!

Ah, Sang-hu!

You have gone back to your true form

While we remain as men, O!

Tzu-kung hastened forward and said, "May I be so bold as to ask what sort of ceremony this is - singing in the very presence of the corpse?"

The two men looked at each other and laughed. "What does this man know of the meaning of ceremony?" they said.
