On one occasion Venerable Udāyī canceled the half-monthly instruction and then set out wandering. The nuns complained and criticized him, “How could Venerable Udāyī do this?” They told the Buddha. “Monks, you shouldn’t cancel the half-monthly instruction and then set out wandering. If you do, you commit an offense of wrong conduct.” At that time there were ignorant and incompetent monks who canceled the half-monthly instruction. They told the Buddha. “A monk who’s ignorant and incompetent shouldn’t cancel the half-monthly instruction. If he does, he commits an offense of wrong conduct.”
