After the banishment transaction was imposed on the followers of Assaji and Punabbasu—requiring them to leave their residence—they did not comply. Instead, they cursed and reviled the monks who had imposed the transaction. So the Buddha had the monks impose a further
saṅghādisesa offense on them to give them one more chance to mend their ways. The Canon does not record whether the affair was ever resolved.
The Buddha continued legislating rules, major and minor, for many years. Some of them were included in the Pāṭimokkha, many were not. Those not included there were gathered in other sections of the Vinaya, called the Khandhakas. As the rules grew in number, some of the monks found them overwhelming. In response to the honest complaint of one such monk, the Buddha affirmed that all the rules had a consistent set of principles underlying them.
On one occasion the Blessed One was staying near Vesālī in the Great Forest. Then a certain Vajjian monk went to him and, on arrival, bowed down to him and sat to one side. As he was sitting there, he said to the Blessed One, “Lord, this recitation of more than 150 training rules comes every fortnight. I cannot train in reference to them.”
“Monk, can you train in reference to the three trainings: the training in heightened virtue, the training in heightened mind, the training in heightened discernment?”
“Yes, lord, I can train in reference to the three trainings: the training in heightened virtue, the training in heightened mind, the training in heightened discernment.”
“Then train in reference to those three trainings: the training in heightened virtue, the training in heightened mind, the training in heightened discernment. As you train in heightened virtue, heightened mind, & heightened discernment, your passion, aversion, & delusion… will be abandoned. You—with the abandoning of passion, the abandoning of aversion, the abandoning of delusion—will not do anything unskillful or engage in any evil.”
Later on, that monk trained in reference to heightened virtue, heightened mind, & heightened discernment. His passion, aversion, & delusion… were abandoned. He—with the abandoning of passion, the abandoning of aversion, the abandoning of delusion—did not do anything unskillful or engage in any evil. —
