By a rescript of October 14 1859 His Holiness Pope Pius IX granted - 300 DAYS' INDULGENCE to all the faithful who with contrite heart and with devotion shall say the following prayer:
O Jesu, vivens in Maria, veni et vive in famulis
tuis, in Spiritus sanctitatis tuae, in plenitudine virtutis tuae, in veritate
virtutum tuarum, in perfectione viarum tuarum, in communione mysteriorum tuorum,
dominare omni adversae potestate in Spiritu tuo ad gloriam Patris. Amen.
O Jesus, who dost live in Mary, come and live in Thy servants, in the spirit of Thine own holiness, in the fulness of Thy power, in the reality of Thy virtues, in the perfection of Thy ways, in the communion of Thy mysteries, - have Thou dominion over every adverse power, in Thine own Spirit, to the glory of Thy Father. Amen.
