“I made up my mind to more serious mortification than ever. When I say mortification, I do not mean that sort of penance the Saints undertake. I was not like those grand souls who practice all kinds of penances from childhood. My mortification consisted in checking my self-will, keeping back an impatient word, doing little things for those around me without their knowing and countless things like that. By these little things, I made ready to become the spouse of Jesus, and I cannot tell you how I grew in abandonment, humility and other virtues as a result.”
