ChapterIII-XII. Sacred Silence
201. It is a general principle that care should be taken in liturgical services to see that "at the proper times all observe a reverent silence."  An opportunity for silence should therefore be provided in the celebration of the liturgy of the hours.
202. In order to receive in our hearts the full sound of the voice of the Holy Spirit and to unite our personal prayer more closely with the word of God and the public voice of the Church, it is permissible, as occasion offers and prudence suggests, to have an interval of silence. It may come either after the repetition of the antiphon at the end of the psalm, in the traditional way, especially if the psalm-prayer is to be
said after the pause (see no. 112), or after the short or longer readings, either before or after the responsory.
Care must be taken to avoid the kind of silence that would disturb the structure of the office or annoy and weary those taking part.
203. In individual recitation there is even greater freedom to pause in meditation on some text that moves the spirit; the office does not on this account lose its public character.
