一位龙王，前世为比丘时曾无意间折断一片叶子，因此忏悔转生为龙身，其女以谜歌寻访佛世，终由青年婆罗门优多罗（Uttara）对答如流而如愿。

A Nāga king who, having been a monk who inadvertently broke a leaf in a past life, was reborn in remorse as a serpent, and whose daughter’s riddle-song, sung in hope of finding a Buddha’s era, was finally answered by the young brahmin Uttara.
