If you seek the Truth, follow the Path, for the Path is also the Truth. Go that way, you must go that way. It is through Christ that you come to Christ.
There is an origin and source of virtue. There is a root of wisdom. And, there is, so to speak, a region of changeless truth. If the soul leaves this region, it lives in darkness but, when it approaches this region, it is enlightened.
(En. in ps. 58, S 1, 18)
Mary was happy because she listened and kept God's word. She kept the truth in her spirit more than in the flesh of her womb.
