Though much work has been done in the fields of Catholic and Oriental spirituality, Protestant spirituality has often been neglected. After a brief biography of A.W. Tozer, this study compares Tozer's mysticism to 35 mystical classics he recommended, such as "John of the Cross", "Teresa of Avila", etc. The focus is on the nature of contemporary Protestant mysticism and the examination of a 20th-century figure operating within a very conservative section of Protestantism who was influenced by mystical prayer. The position which Tozer reached may be of value to others also having to cope with the pressures of contemporary life in a metropolitan environment.
