1.70

問：「僧結界竟，後來僧共住，不持衣，失衣不？」答：「不失。當結界時以通三世僧故。」

Question: "When the saṅgha has finished demarcating a sīmā, if later-arriving monks dwell together with them and do not hold their robes, do they lose their robes?" Answer: "They do not lose them. Because when demarcating the sīmā, it embraces the saṅgha of the three periods of time."
