"dense darkness is obscuring your mind"
Jesus: Well, My child, this time you have told Me a good deal. I realize how painful it is not to be understood, and especially by those whom one loves and with whom one has been very open. But suffice it to know that I understand all your troubles and misery. I am pleased by the deep faith you have, despite everything, in My representatives. Learn from this that no one will understand a soul entirely — that is beyond human ability. Therefore, I have remained on earth to comfort your aching heart and to fortify your soul, so that you will not falter on the way. You say that a dense darkness is obscuring your mind. But why, at such times, do you not come to Me, the light who can in an instant pour into your soul more understanding about holiness than can be found in any books? (Diary, 1487).
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
