This prayer teaches us how to treat material things.
March 3, 1914
AS the day of departure draws near, I enter into a sort of calm collectedness; I turn with an affectionate seriousness towards all those thousand little trifles which surround us and which have silently played during so many years the part of faithful friends; I thank them with gratitude for all the charm they have been able to impart from the outside to our life; I wish, if they are destined to pass for a long or a brief period into other hands than ours, that those hands may be gentle to them and may feel all the respect that is due to what Thy divine Love, O Lord, has made to emerge from the dark inconscience of chaos.
Then I turn towards the future and my regard becomes still more grave. What it has in store for us I do not know and am not anxious to know; outer circumstances have no importance at all; I would only wish that it may be the beginning of a new inner period, in which, more detached from material things, we may be more conscious of Thy law and more solely consecrated to its manifestation; that it may be a period of a greater light, a greater love, a more perfect devotion to Thy cause.
In a silent adoration I contemplate Thee.
