Dhammapada Verse 106
The Story of Thera Sariputta's Uncle
On one occasion, Thera Sariputta asked his uncle the brahmin whether he was doing any meritorious deeds. The brahmin answered that he was making offerings to the value of one thousand Kahapanas every month to the Nigantha ascetics, 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. So saying, he took his uncle the brahmin to the Buddha, and requested the Buddha to expound the Dhamma, which would surely take one to the Brahma world.
