It is not lust alone that one should be afraid of in the life of the world. There is also anger. Anger arises when obstacles are placed in the way of desire.
Lust and self-mutilation are closely related impulses. There are also self-mutilators among knowers: they do not want to be creators under any circumstances.
There are many who lust for the simple answers of doctrine or decree. They are on the left and right. They are not confined to a single part of the society. They are terrorists of the mind.
