A prayer from The Blessed Sacrament Prayer Book by Fr. Lasance (pg. 508)
O Virgin Mary, grant that the recitation of thy Rosary may be for me each day, in the midst of my manifold duties, a bond of unity in my actions, a tribute of filial piety, a sweet refreshment, and encouragement to walk joyfully along the path of duty. Grant, above all, O Virgin Mary, that the study of thy Fifteen Mysteries may form in my soul, little by little, a luminous atmosphere, pure strengthening, and fragrant, which may penetrate my understanding, my will, my heart, my memory, my imagination, my whole being. So shall I acquire the habit of praying while I work, without the aid of formal prayers, by interior acts of admiration and supplication or by aspirations of love. I ask this of thee, O Queen of the most Holy Rosary through Saint Dominic, thy son of predilection, the renowned preacher of thy mysteries and the faithful imitator of thy virtues.
Indulgence of 300 days once a day. - Pius X, March 15, 1907
