A sutta dating from early in the Buddha's teaching career. A wanderer, disappointed in the teachings he has received from other teachers, approaches the Buddha with his questions.
A follower of Devadatta slanders Ven. Sāriputta and Ven. Moggallāna and, after suffering a painful disease, falls into hell. The sutta then gives a graphic description of the sufferings awaiting him there.
Not all dualities are misleading. This sutta teaches ways to contemplate the duality of the origination and cessation of stress and suffering so as to reach awakening.
