Spirituality is the art of achieving union with God, and consists of two branches—asceticism and mysticism, the mortification of the self and that contemplation by means of which the soul makes contact with ultimate Reality. Mortification without contemplation, and contemplation without mortification are both useless, and may even be positively harmful. That is why all genuine mystical literature is also ascetical literature, while all good ascetical literature (such as “The Imitation of Christ”) treats also, explicitly or by implication, of mystical prayer.
