Know, my beloved brother, that any spiritual or worldly knowledge that does not lead you to humiliation and to the feeling that you are ignorant, is a false deceitful knowledge. It is a blow from the devil to make you turn from asking, requiring and knocking at the door... Feel then, my brother, that you are ignorant as the Holy Bible says, "If anyone among you seems to be wise in this age, let him become a fool that he may become wise" (1 Cor. 3:18)
