Know that all that Allah has allocated for humankind is for the purpose of benefiting them; either to bring forth a benefit such as the desire for food, or to prevent a harm such as the capability of anger. That said, when the desire for food is in excess it becomes gluttony and hence, harmful. On a similar note anger when imbalanced within a person becomes mischievous.

The purpose of this book is to employ the law of soundness and correctness through the channels of the mind and the heart, and to constrain Hawa so that it does not cause harm, and to treat Hawa that has been acted upon yet opposes the law of soundness and correctness. For this reason, I have divided this book into thirty chapters.
