This prayer is the prayer of perfect contemplation and the serenity that follows.
May 2, 1914
BEYOND all human conceptions, even the most marvellous, beyond all human feelings, even the most sublime, beyond the most magnificent aspirations and the purest elans, beyond Love, Knowledge and the Unity of the Being, I would enter into a constant communion with Thee, O Lord. Free from all trammels, I shall be Thyself; it will be Thou seeing the world through this body; it will be Thou acting in the world through this instrument.
In me is the calm serenity of perfect certitude.
