O Sacred Heart of Jesus, I unite my heart to the spirits of the blessed, that with them it may sing to Thy glory before the throne of God. The Lamb that was slain is worthy to receive power, and divinity, and wisdom, and strength, and glory, and benediction. By Thy virtue guard my heart, and preserve it from the stains of its own sinful desires. Amen.
