The ancient spiritual tradition of the Church,
explicitly connects the enclosed-contemplative life to the prayer of
Jesus "on the mountain", or solitary place not accessible to all but
only to those whom he calls to be with Him, apart from the others.
The enclosure therefore, even in its physical form, is a special way of
being with the Lord, of sharing in Christ's emptying of Himself by
means of a radical poverty, expressed in renunciation not only of
things but also of space, of contacts, of so many benefits of creation.
Pope John Paul II, Verbi Sponsa
