Certainly an interesting book about the mystical interpretation of taharah, purification. Ibn Al-Arabi in this first book explains the mystical concepts or rather mystical interpretations of the purification ritual. For every rule he describes what each school required and than puts forward his position and defends it both in inner and outer meaning. I found the explanations on comperative part of the rituals a littel weak and short. I believe for comperative studies and to get better understanding of the reasonings behind each school of thoughts, Ibn Rushd's book to be a better source. For the student of mystism certainly this is a must read book.
