This prayer teaches us about patience and how to call upon the Divine.
July 21, 1913
…YET what patience is needed! How imperceptible the stages of progress! . . . Oh! how I call Thee from the very depths of my heart, True Light, Sublime Love, Divine Master who art the source of our light and of our living, our guide and our protector, the Soul of our soul and the Life of our life, the Reason of our being, the supreme Knowledge, the immutable Peace!”
