Sufism is the inner dimension of Islam, expressing hidden archetypes in concrete symbols. To the Sufi, both the ritual of the worshipper and the work of the craftsman evoke the life which resides within all things: the preparedness of matter to answer the call of God. Through the Sufi themes of the descending arc of Creation, the formation of the human soul, and its return through the ascending arc of the Quest, this book brings to light the spiritual reality which underlies the forms and rhythms of the Islamic tradition.
