I’ve always smiled at the thoughtfulness of St. Benedict’s very detailed rules for monastic living. Chapter 22 of The Rule takes up “The Sleeping Arrangements of the Monks.” In keeping with the spirit of communalism, Benedict stipulates:
“If possible, all are to sleep in one place, but should the size of the community preclude this, they will sleep in groups of ten or twenty”.
But considering that the monks are still males who are isolated from females and who have taken a vow of chastity, he adds:
“under the watchful care of seniors.”
Presumably, seniors are suitable for this duty as they have passed the point of needing to indulge their physical urges. Even so:
“A lamp must be kept burning in the room until morning.”
(Perhaps not uncoincidentally, the next section of the Rule is titled “Excommunication for Faults.”)
