1.131

問：「受戒盡十三事，後諸戒師和尚不續教戒。得戒具不？」答：「若師不教誡，至十五日說戒專心聽受，便得具足。」

Question: "Having received the precepts covering all thirteen matters, if afterwards the precept masters and upādhyāya do not continue to instruct him in the precepts, are his precepts complete?"
Answer: "If the masters do not instruct him, when on the fifteenth day the precepts are recited, if he focuses his mind on listening and accepting them, they become complete."
