This is the shortest and yet the most powerful of all prayers. It has one word, the Holy Name of:

Jesus

While reflecting on the Holy Name of Jesus, the faithful repeats over and over the Holy Name of "Jesus" in a pious manner. Many of the Saints had a great love for the Holy Name of Jesus. Among a few, there was the Apostle Paul, St. Thomas Aquinas, St. Augustine, St. Dominic, St. Francis of Assisi, St. Francis de Sales and St. Ignatius of Loyola.

The Holy Name of Jesus represents the incarnation of God among men on earth. It is the Name above all names. It is the Most Holy Name that deserves the greatest honour and glories, above all other feasts. Because of our living hope in the Name of "Jesus", we have the assurance of our resurrection and eternal salvation.

Before the change of Church regulations regarding Indulgences, each time the name of Jesus was invoked, the prayerful soul gained 300 days indulgence that could be applied towards the souls in Purgatory.
