Dhammapada Verse 107
The Story of Thera Sariputta's Nephew
On one occasion, Thera Sariputta asked his nephew, a brahmin, whether he was doing any meritorious deeds. His nephew answered that he had been sacrificing a goat in fire-worship every month, hoping to get to the Brahma world in his next existence. Thera Sariputta then explained to him that his teachers had given him false hopes and that they themselves did not know the way to the Brahma world.
