月光童子

月光兒 The son of an elder of the capital of Magadha, who listening to heretics and against his son's pleadings, endeavoured to destroy the Buddha in a pitfall of fire, but, on the Buddha's approach, the fire turned to a pool and the father was converted; the son was then predicted by the Buddha to be king of China in a future incarnation, when all China and the Mongolian and other tribes would be converted, v. 月光童子經.
