… Afterwards, I was thinking about what Jesus had told me, and I said to myself: “How can this be put into practice?” And Jesus, returning, added: "My daughter, in order to know the Truths, it is necessary to have the will, the desire to know them. Imagine a room in which the shutters are closed: no matter how much sun there may be outside, the room remains always in the dark. Now, opening the shutters means wanting light. But this is not enough, if one does not take advantage of the light to reorder the room, dust it, and put himself to work, so as to not kill the light which is given, and become ungrateful. In the same way, it is not enough to have the will to know the Truths if, at the Light of the Truth which illuminates, one does not try to dust himself of his own weaknesses, reorder himself according to the Light of the Truth he knows, and put himself to work together with the Light of Truth, making of it his own substance, in such a way that the Light of the Truth which he has absorbed may shine through his mouth, through his hands, through his bearing. It would be as if he killed the Truth; and by not putting it into practice, it would be like remaining in total disorder before the light. Poor room full of light, but all messed up, upside down, in total disorder, with a person in it who does not take the care of reordering it — how pitiful would it not be? Such is one who knows the Truths, and does not put them into practice.
“However, know that Simplicity enters into all truths as the first nourishment. If the Truths were not simple, they would not be Light, and they could not penetrate into human minds to enlighten them; and where there is no light, objects can not be distinguished. Simplicity is not only light, but it is like the air that one breathes which, though it cannot be seen, gives respiration to all; and if it wasn’t for the air, the earth and everyone would remain without motion. Therefore, if the virtues, the truths, do not carry the mark of Simplicity, they will be without light and without air."
