1.1018

沙彌籌中。通前四唱，並須三說。今時一遍唱已，三唱後句，即當三說；此非正法，出自愚情。或恐延時，準後諸白，乍可一說；此告眾法，非同羯磨三一永定，單說無損。乃下，恐有大僧傳沙彌欲，故須告問；此謂界無同類，故開之耳。

In [the section on] "Tallies for the Śrāmaṇeras": Together with the preceding four announcements, all must be spoken three times. Nowadays, after chanting it once, they chant the final phrase three times, treating that as the threefold pronouncement; this is not the correct Dharma, but arises from ignorant inclinations. Or perhaps fearing it takes too long, based on the subsequent jñaptis, it may tentatively be spoken once; this is a procedure for announcing to the assembly, not the same as a karmavācanā which is permanently fixed as threefold or single, so a single pronouncement causes no harm. From "Or…" onward: fearing that a bhikṣu might convey the consent (chanda) of a śrāmaṇera, it must therefore be announced and asked; this refers to when there are none of their own class within the boundary, which is why this exception is granted.
