This novena prayer, although short is sufficient. It would be better of course to add, if time permits, three Hail Marys or say five times the Our Father, Haily Mary and Glory be to the Father, or to use some of the many well-loved novena prayers from other sources. Remember that prayers must be said with the lips in order to gain the indulgences. This novena begins nine days before the feast of the Sacred Heart is celebrated. (The Feast is the Friday after the octave day of Corpus Christi.)
O Most Sacred Heart of Jesus, pour down Your blessings abundantly upon Your Church, upon the Supreme Pontiff, and upon all the clergy; give perseverance to the just, convert sinners, enlighten unbelievers, bless our parents, friends, benefactors, help the dying, free the souls in purgatory and extend over all hearts the sweet empire of Your love. Amen.
