There are no words to describe the beauty of this book. Unique style: It's enough to read half a sentence to know it's Abu Hayyan al-Tawhidi. Abu Hayyan dialectically incorporates the Sufi tradition and reproduces it in another form, different, specific to Abu Hayyan's experience. The result is a book of Sufi thoughts and soliloquies that are far removed from the style of Sufi mystics.
