If we hope to move beyond the superficialities of our culture - including our religious culture - we must be willing to get down into the recreating silences, into the inner world of contemplation. In their writings, all of the masters of meditation strive to awaken us to the fact that the universe is much larger than we know, that there are vast unexplored inner regions that are just as real as the physical world we know so well. They tell us of exciting possibilities for new life and freedom. They call us to adventure, to be pioneers in this frontier of the Spirit. Though it may sound strange to modern ears, we should without shame enroll as apprentices in the school of contemplative prayer.
The above is taken, verbatim, from my battered 1984 copy of Richard Foster's 'Celebration of Discipline,' which I'm re-reading for the umpteenth time.
