How do so many other religious who are confined in cloistered discipline get along? They seldom go out, they live in contemplation, their food is poor, their clothing coarse, they work hard, they speak but little, keep long vigils, rise early, pray much, read frequently, and subject themselves to all sorts of discipline. Think of the Carthusians and the Cistercians, the monks and nuns of different orders, how every night they rise to sing praise to the Lord. It would be a shame if you should grow lazy in such holy service when so many religious have already begun to rejoice in God.

Kempis, Thomas à. The Imitation of Christ
