1.318

（佛言：「受戒人不得在空、隱沒、離見聞處。若在界外，其和尚及足數人，亦不得在空，乃至界外。」佛言：「當安欲受戒者眼見、耳不聞處立。」）

(The Buddha said: “The ordinand must not be in mid-air, in a hidden place, or outside sight and hearing. If he is outside the boundary, his upādhyāya and those completing the quorum also must not be in mid-air, nor outside the boundary.” The Buddha said: “One should place the candidate wishing to receive the precepts standing where he can be seen by the eyes but not heard by the ears.”)
