“Yesterday, with the same pleasure as I always have, I received your letter of the 22nd. You are perfectly right, I think, in what you say about the necessity and difficulty in influencing souls from within. What gives me great satisfaction in this, so far as it affects you, is to see that you are being led by the necessities inherent in your life and the duties of your position to fall back on the Milieu divine, and to seek union with God as the first, and almost consciously experienced, condition for action.
It is thus, through a sort of deep rift, that God enters into the tangible reality of all that is most human in your life;—and once He has made his way in, he will never cease, you’ll find, gradually to extend His dominion until He invades anything.”
