Among the religious families, there are those like the Benedictines and Cistercians, who live more in community. Others live in greater solitude. Camaldulites and Carthusians belong to the latter. The monks and the nuns of the Carthusian Order, while living separately in their own monasteries, share the same rule and follow a unique model in the person of their founding Father, Saint Bruno.
The Carthusian does not live alone as the Carthusian monastery is a community. Nevertheless, he will pass the greater part of his life in his cell where he prays, works, takes his meals, and sleeps. During the course of the week, he only leaves three times a days for offices and communal mass: in the middle of the night, the Night Office, the morning Eucharist and Vespers towards the night.
