The outward beauty of the liturgy must not seduce us into forgetting that sobriety in prayer is a very important feature in Orthodoxy. In the Way of a Pilgrim a village priest gives some very authoritative advice on prayer: ‘If you want it to be pure, right and enjoyable, you must choose some short prayer, consisting of few but forcible words, and repeat it frequently, over a long period. Then you will find delight in prayer.’ The same idea is to be found in the Letters of Brother Lawrence: ‘I do not advise you to use multiplicity of words in prayer; many words and long discourses being often the occasions of wandering.’
John of Kronstadt was asked once how it was that priests, in spite of their training, experience wandering, intrusive thoughts, even in the course of the liturgy. The answer was: ‘Because of our lack of faith.’ We have not faith enough, faith being understood in the terms of St Paul as ‘the evidence of things not seen’ (Heb II: I). But it would be a mistake to think that those distracting thoughts all come from outside; we must face the fact that they come from our own depths: they are our continual inner preoccupations coming to the fore, they are just the thoughts that usually fill our life, and the only way to get radically rid of unworthy thoughts is to change our outlook on life fundamentally.
Again, as Brother Lawrence puts it in his eighth letter: ‘One way to recollect the mind easily in the time of prayer, and preserve it more in tranquility, is not to let it wander too far at other times; you should keep it strictly in the presence of God; and being accustomed to think of him often, you will find it easy to keep your mind calm at the time of prayer, or at least to recall it from its wanderings.
As long as we care deeply for all the trivialities of life, we cannot hope to pray wholeheartedly; they will always colour the train of our thoughts. The same is true about our daily relations with other people, which should not consist merely of gossip but be based on what is essential in every one of us, otherwise we may find ourselves unable to reach another level when we turn to God. We must eradicate everything meaningless and trivial in ourselves and in our relations with others, and concentrate on those things we shall be able to take with us into eternity.
