Song of Songs of Solomon is Madame Guyon's commentary, of sorts, on the Songs of Solomon. Imprisoned and persecuted for her mystic views, she provides her own allegorical and somewhat mystical interpretation of Songs of Solomon. She interprets the book in terms of Christ and the Church. In particular, she focuses on the "Spiritual Marriage"--where the soul has "permanent and lasting possession" of the divine. Her Song describes the different stages that the believer goes through on the way to maturation in Christ and the possession of the divine. Although Madame Guyon's interpretation is somewhat controversial, it remains powerful and is able to move one's heart towards God.
