O my God, Trinity whom I adore, help me forget myself entirely so to establish myself in you, unmovable and peaceful as if my soul were already in eternity. May nothing be able to trouble my peace or make me leave you, O my unchanging God, but may each minute bring me more deeply into your mystery! Grant my soul peace. Make it your heaven, your beloved dwelling and the place of your rest. May I never abandon you there, but may I be there, whole and entire, completely vigilant in my faith, entirely adoring, and wholly given over to your creative action.This is at the end of the section of the Catechism about the Trinity. The entire section kept astounding me with the mystery of it all, but this prayer keeps drawing me back again and again. It is so perfect.
Prayer of Blessed Elizabeth of the Trinity
