True Knowledge of Self
I saw Jesus, and from His Heart there issued those same two rays, which enveloped me, whole and entire. At the same moment, all my torments vanished. My daughter, the Lord said, know that of yourself you are just what you have gone through, and it is only by My grace that you are a participant of eternal life and all the gifts I lavish on you. And with these words of the Lord, there came to me a true knowledge of myself. Jesus is giving me a lesson in deep humility and, at the same time, one of total trust in Him. My heart is reduced to dust and ashes, and even if all people were to trample me under their feet, I would still consider that a favor (Diary, 1559).
Devotion to the souls in Purgatory contains in itself all the works of mercy, which supernaturalized by a spirit of faith, should merit us Heaven. de Sales
