called "the rosary … a living thing, a school of contemplation" in pt. 3 ch. 6 "The Knowledge of God in Proficients"
of his Three Ages of the Interior Life
The proficient obtained a deeper self-knowledge while passing through the period of prolonged aridity which marks the second conversion. With this knowledge of his poverty, of his spiritual indigence, there grows within him by contrast a quasi-experimental knowledge of God, not only in the mirror of the sensible things of nature, of the parables, of exterior worship, but in the spiritual mirror of the mysteries of salvation with which he familiarizes himself. These mysteries, which are those of the incarnation of the Word, of the redemption, of eternal life, the rosary daily places before our eyes by recalling to us the Savior’s childhood, His sorrowful passion, His resurrection and ascension. If the proficient is faithful, he goes beyond the sensible aspect of these mysteries, he attains all that is spiritual in them, the infinite value of the merits of Christ; then the rosary is no longer the mechanical recitation of the Hail Mary, but a living thing, a school of contemplation. The joyful mysteries bring us the good news of the annunciation and the nativity of our Savior, which constitute true, enduring, and deep joys far above the pleasures of the world and the satisfactions of pride. Likewise, in the midst of our sufferings, which are often without reason, at times overwhelming, almost always badly borne, the sorrowful mysteries repeat to us that our sins should be the object of our grief. They make us desire to know them better, to experience a sincere sorrow for them, and thus we begin to comprehend the profound meaning and the infinite value of Christ’s passion and its effects in our lives. Finally, in the midst of the instability and uncertainties of this life, the glorious mysteries recall to us the immutability and the perfect happiness of eternal life, which is the goal of our journey.
