Oh, God help my daughters, how many souls the devil must have ruined in this way! They think that all these misgivings, and many more that I could describe, arise from humility, whereas they really come from our lack of self-knowledge. We get a distorted idea of our own nature, and, if we never stop thinking about ourselves, I am not surprised if we experience these fears and others which are still worse. It is for this reason, daughters, that I say we must set our eyes upon Christ our Good, from Whom we shall learn true humility, and also upon His saints. Our understanding, as I have said, will then be ennobled, and self-knowledge will not make us timorous35 and fearful; for, although this is only the first Mansion, it contains riches of great price, and any who can elude the reptiles which are to be found in it will not fail to go farther. Terrible are the crafts and wiles which the devil uses to prevent souls from learning to know themselves and understanding his ways.
