Chapter 7, Part 1 - Chuang Tzu

Nieh Ch'ueh Was Questioning Wang Ni. Four times he asked a question and four times Wang Ni said he didn't know. Nieh Ch'ueh proceeded to hop around in great glee and went and told Master P'u-i.

Master P'u-i said, "Are you just now finding that out? The clansman Yu-yu was no match for the clansman T'ai. The clansman Yu-yu still held on to benevolence and worked to win men over. He won men over all right, but he never got out into [the realm of] `notman.' The clansman T'ai, now - he lay down peaceful and easy; he woke up wide-eyed and blank. Sometimes he thought he was a horse; sometimes he thought he was a cow. His understanding was truly trustworthy; his virtue was perfectly true. He never entered [the realm of] `not-man.' "
