"The nature of the icon cannot be grasped by means of pure art criticism, nor by the adoption of a sentimental point of view. Its forms are based on the wisdom contained in the theological and liturgical writings of the Eastern Orthodox Church and are imtimately bound up with the experience of the contemplative life. The present work is the first of its kind to give a reliable introduction to the spiritual background of this art. The introduction into the meaning and language of the icons by Ouspensky imparts to us in an admirable way the spiritual conceptions of the Eastern Orthodox Church which are often so foreign to us, but without the knowledge of which we cannot possibly understand the world of the icon." -- Back cover.
