The Rule of St. Benedict - Chapter 52. The Oratory Of The Monastery

(1) The oratory ought to be what it is called, and nothing else is to be done or stored there.

(2) After the Work of God, all should leave in complete silence and with reverence for God,

(3) so that a brother who may wish to pray alone will not be disturbed by the insensitivity of another.

(4) Moreover, if at other times someone chooses to pray privately, he may simply go in and pray, not in a loud voice, but with tears and heartfelt devotion.

(5) Accordingly, anyone who does not pray in this manner is not to remain in the oratory after the Work of God, as we have said; then he will not interfere with anyone else.
