"Whatever one may think of the value of communal celebration with all kinds of song and self-expression--and these certainly have their place--the kind of prayer we here speak of as properly 'monastic' (though it may also fit into the life of any lay person who is attracted to it) is a prayer of silence, simplicity, contemplative and meditative unity, a deep personal integration in an attentive, watchful listening of 'the heart.' The response such prayer call forth is not usually one of jubilation or audible witness: it is a wordless and total surrender of the heart of silence."
(CONTEMPLATIVE PRAYER, page 29-30)
