Little Miss Sunshine,

Here's reference to repetitive prayer, all our prayers should be from the heart. Someone can better share than I.
The Rosary has 3 main prayers repeated. You pray them
as you meditate on Our Lord and His mother's life with Him.

Consider the prayers spoken of in Revelation 4:8 offered day and night without ceasing: "Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!" Another repetitious prayer pleasing to God is contained in Psalm 136: "For his steadfast love endures for ever." This phrase is repeated over twenty-five times. Finally, Matthew 26:44 tells us that Jesus himself prayed the same prayer three times in the garden in Gethsemane.
