When you examine your conscience (attention to what I am going to tell you) do not go too far; look at it as we look at the seashore from the top of the Alps or the Pyrenees, lightly, without going into details. If you do not see anything clearly and certainly wrong, go ahead and be at peace with your God. Mind this, I repeat, and do tell me how you are faring, because the devil could trick you and do you serious hard with his false doctrine and suggestions. This union produces peace of mind; then search for peace. Let nothing disturb you, be it good or bad.
Letter to Juana Gratia (1857)
