The elder warned us not to pray while our hearts were steeped in unprayerful feelings, without thoughts wandering as they chose. Prayer is not a mechanical activity, but a confrontation, a conversation with the Holy Presence. Pray humbly, then, in awe of God.
People talk about the silence of nature, but of course there is no such thing. What they mean is that OUR voices are still, OUR noises are absent.
