僧祇云。燃燈不得卒入房。應先在外唱言。諸大德燈入（記云。此的眾。若今禪居及講院寮舍也。若卒將入恐暗中比丘威儀不整）。至滅燈時。亦不得卒滅先以手遮燈告曰。滅燈。眾若默方可滅（此慮眾僧收拾不辨）不得用口吹。當將筯敧燼折去之（攲音𮗋。言取物也記作𮧡非也）。

The Mahāsāṃghika says: 'When lighting a lamp, one must not suddenly enter a room. One should first call out from outside: "Venerable ones, a lamp is coming in!"' (The Record states: 'This points to a group, like the present-day Chan residences and the dormitories of lecture cloisters. If one suddenly brings it in, one fears that the monks in the dark might not have their deportment in order.') 'When it is time to extinguish the lamp, one must also not extinguish it suddenly. One should first shade the lamp with a hand and announce: "Extinguish the lamp!" If the assembly remains silent, only then may it be extinguished' (this is out of concern that the monks might not have finished putting things in order). 'One must not blow it out with the mouth; one should take chopsticks, slant the charred wick, and snap it off' (qi is pronounced qi; it means to take up an object. The Record writing it as 𮧡 is incorrect).
