This practical guide aims to identify and integrate one's shadow, all of the material in the unconscious mind that was repressed over the first half of life and emerges to wreak havoc in our lives. The work is grounded in the teaching of cultural anthropologist Angeles Arrien, especially in her books The Four Fold Way and the Second Half of Life, and psychiatrist Carl Jung. The book is structured as a self-help workbook that can help with personal transformation in individual work or can be used in small groups. Some authors believe that the psychological work on the shadow is a necessary component for spiritual work.
