A dying lay disciple, Dīghāvu, invites the Buddha to his sickbed. Already established in the four factors of stream entry and in deep insight into impermanence, unsatisfactoriness, and dispassion, he receives a final exhortation to keep his mind on the Dhamma. After his passing, the Buddha declares Dīghāvu a non-returner who will attain final Nibbāna.
