“If you’re staying in the wilderness, you should agree to give the half-monthly instruction. You should make an appointment, saying, ‘I’ll return here.’” At that time there were monks who agreed to give the half-monthly instruction without informing. They told the Buddha. “When you have agreed to give the half-monthly instruction, you should inform. If you don’t, you commit an offense of wrong conduct.” At that time there were monks who had agreed to give the half-monthly instruction, but did not return to give it. They told the Buddha. “You should return to give the half-monthly instruction. If you don’t, you commit an offense of wrong conduct.”
