FOURTH GLORIOUS MYSTERY: The Assumption.
The Blessed Mother is united with her Divine Son in heaven.

Blessed art thou of the most high God above all the women upon the earth; and blessed be the Lord God, which hath created the heavens and the earth, which hath directed thee to the cutting off of the head of the chief of our enemies. ... Thou hast done all these things by thine hand: thou hast done much good to Israel, and God is pleased therewith: blessed be thou of the Almighty Lord for evermore. And all the people said, So be it. (Jdt 13,18-20; 15,10)
