Among the several rites and manners of paying honor to the Blessed Mary, some are to be preferred, inasmuch as we know them to be most powerful and most pleasing to our Mother; and for this reason we specially mention by name and recommend the Rosary.
The common language has given the name of corona to this manner of prayer, which recalls to our minds the great mysteries of Jesus and Mary united in joys, sorrows, and triumphs.
The contemplation of these august mysteries, contemplated in their order, of fords to faithful souls a wonderful confirmation of faith, protection against the disease of error, and increase of the strength of the soul. The soul and memory of him who thus prays, enlightened by faith, are drawn towards these mysteries by the sweetest devotion, are absorbed therein and are surprised before the work of the Redemption of mankind, achieved at such a price and by events so great.
The soul is filled with gratitude and love before these proofs of Divine love; its hope becomes enlarged and its desire is increased for those things which Christ has prepared for such as have united themselves to Him in imitation of His example and in participation in His sufferings.
The prayer is composed of words proceeding from God Himself, from the Archangel Gabriel, and from the Church; full of praise and of high desires; and it is renewed and continued in an order at once fixed and various; its fruits are ever new and sweet.
~ Pope Leo XIII- Encyclical Octobri Mense -on the Holy Rosary ~
