In the booklet ‘The Truth About Dynamic Prayer’ Dr. George King explains the difference between saying a prayer in an ordinary way versus a dynamic way:

“The main difference between prayer—shall we call it ordinary prayer, and shall we call it dynamic prayer—is the depth of expression. One is a shallow appeal, as though you were asking the greengrocer for two pounds of apples, and the other a deep expression of  your inner feeling—a belief in yourself that you are capable of praying in this way and that this is the way which will bring results.”

Saying prayers dynamically is far more powerful than saying a prayer with empty words. We can use this technique when we practice The Twelve Blessings.
