O JESUS, vivens in Maria, Veni et vive in famulis Tuis, In spiritu sanctitatis Tuae, In plenitudine virtutis Tuae, In veritate virtutum Tuarum, In perfectione viarum Tuarum, In communione mysteriorum Tuorum; Dominare omni adversae potestati, In Spiritu Tuo, ad gloriam Patris. Amen. O JESUS, living in Mary, Come and live in Thy servants, In the spirit of Thy sanctity, In the fulness of Thy strength, In the reality of Thy virtues, In the perfection of Thy ways, In the communion of Thy mysteries.
