Al-Ghazzali describes the concept of intention in great detail, its true nature and how the intention of the believer is better than his deed. He explores whisperings of the self, evil inspiration and bad thoughts and then those deeds that change according to intention and how the admirable servant does what he does for the sake of God. In regard to sincerity, he describes its true nature and then goes on to describe truthfulness. This is Book XXV of Part Four of the Alchemy of Happiness entitled The Deliverers.
