Mahā Vacchagottasutta untranslated

Mahā Vacchagottasutta. The Paribbājaka Vacchagotta visits the Buddha at Veḷuvana and asks him to expound right and wrong. The Buddha does so, and adds that those who follow his teaching are sure of deliverance and of birth in happy worlds and are destined for Nibbāna. Vacchagotta is very pleased and seeks admission to the Saṅgha, but the Buddha says that he must first pass four months as a probationer. At the end of that time he enters the Saṅgha and the Buddha further expounds the Dhamma to him. Shortly after he becomes an Arahant. MN.i.489-97.
