This node interprets the prose parable in Section 10 of Jami's Baharestan. A blind man walks on a dark night carrying a lamp in his hand and a jug on his shoulder. A meddler mocks him, asking what use a lamp could be to one for whom light and darkness are alike. The blind man laughs and answers that the lamp is not for his own sake but for the sightless, foolish-hearted people like the questioner, so that they will not collide with him and shatter his jug. The closing verses sharpen the satire: no one can tell one fool from another, even were he more learned than Avicenna, and the one who taunts the blind man is himself the truly blind one, for the blind man at least sees clearly to his own affairs. The parable teaches that practical self-awareness and prudence are a truer form of sight than boasted learning, and it rebukes those who judge others while lacking insight into themselves.
