The Explanation on the Festering
At one time the Buddha was staying in the land of the Sakyans, near Kapilavatthu in the Banyan Tree Monastery. Now at that time a new town hall had recently been constructed for the Sakyans of Kapilavatthu. It had not yet been occupied by an ascetic or brahmin or any human at all. Then the Sakyans of Kapilavatthu went up to the Buddha, bowed, sat down to one side, and said to him, “Sir, a new town hall has recently been constructed for the Sakyans of Kapilavatthu. It has not yet been occupied by an ascetic or brahmin or any human at all. May the Buddha be the first to use it, and only then will the Sakyans of Kapilavatthu use it. That would be for the lasting welfare and happiness of the Sakyans of Kapilavatthu.” The Buddha consented with silence.
