“All knowledge leads to self-knowledge.”

“To know how to put what knowledge in which place is wisdom (hikmah). Otherwise, knowledge without order and seeking it without discipline does lead to confusion and hence to injustice to one's self.”

“If knowledge does not liberate the self from the self, then ignorance is better than such knowledge.”

“Self-knowledge is the only basis of true knowledge.”

“Knowlege of God without knowledge of man's wretchedness leads to pride. Knowledge of man's wretchedness without knowledge of God leads to despair. Knowledge of Jesus Christ is the middle course, because by it we discover both God and our wretched state.”

“Knowledge of the self is the mother of all knowledge. So it is incumbent on me to know my self, to know it completely, to know its minutiae, its characteristics, its subtleties, and its very atoms.”
