46.58

The Emperor and Lingsu were discussing Daoism in an informal palace hall. A person in a blue kerchief and tattered clothes directly ascended the hall without bowing. Lingsu recognized him and said, 'Elder Brother Lü has come again!' He immediately hurried to the corner of the hall and vanished. There was only a poem written in chalk, which said: 'Loud and broad talk as if no one were there; / What a pity that the enlightened monarch has not encountered the real. / If you wish to ask about good and ill fortune of past and present, / You must guard against the spring of Wu-Wei and Bing-Ding.' The Emperor knew it was the arrival of Dongbin and sighed over it. Later, everything turned out as he had predicted.
