《太平广记·卷一百一十五·报应十》
父亲答应了他。从此他便虔诚洁净焚香修行，整夜不怠，过了几年，忽然能说话了，声音清晰，超出于同辈人。
父许之，由是虔洁焚修，夙夜无怠，经数载，倏尔能言，抗音清辩，超于群辈。
His father agreed to his request. From then on, he devoutly and purely burned incense and practiced cultivation, never slacking off all night long. After a few years, he suddenly could speak. His voice was clear and exceeded that of his peers.
