LI. gives directions for monastic discipline.  “Let the superintendent exert discipline after the manner of a physician treating his patients.  He is not angry with the sick, but fights with the disease, and sets himself to combat their bad symptoms.  If need be, he must heal the sickness of the soul by severer treatment; for example, love of vain glory by the imposition of lowly tasks; foolish talking, by silence; immoderate sleep, by watching and prayer; idleness, by toil; gluttony, by fasting; murmuring, by seclusion, so that no brothers may work with the offender, nor admit him to participation in their works, till by his penitence that needeth not to be ashamed he appear to be rid of his complaint.”
