The monastery is one of the few forms of communal living that has survived the test of time. The orders of monks have evolved sets of rules which hold the communities together. The most famous of all monastic rules was written by St Benedict, whose 1,500th anniversary is being celebrated this year. Over 800 communities worldwide still order their lives according to the detailed instructions he laid down. Everyman follows the Cistercian monks of Mount St Bernard Abbey, Leicestershire, through one day lived according to the Rule: from waking at 3.15 am to sleeping at 8.0 pm.
