Mary did the will of the Father, and that is why it is greater for her to have been a disciple of Christ than to have been the mother of Christ.
God wished to sow in every soul the seeds of intelligence and wisdom.
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)
