Nangalisa Jātaka (No. 123)
Once the Bodhisatta was a Brahmin teacher, and among his
five hundred pupils was a very foolish but devoted youth, who had a knack of
saying the wrong thing. Hoping to cure him, the Bodhisatta asked him to report
anything which he saw.
One day the youth saw a snake, and on being asked by the
Bodhisatta how it looked, he answered, "like the shaft of a plough" (nangalisa).
The Bodhisatta thought the simile good, but when it was used again about an
elephant, a sugar cane, molasses and even curds and milk, he realized that the
boy was hopeless. The story was told in reference to
Lāludāyi, who never made an
appropriate remark. Lāludayi is identified with the youth. J. i.446ff.
