Mostly, prayer is pure desire of the heart. Real prayer is not repeating a bunch of words by rote. Those words DO become a prayer if they are the true desire of your heart; if you feel them and long for them as you say them. If the words are really what you want to happen then engage your heart, mind and spirit in the recitation of the words and they are a real prayer.
There is value in the repetition of those well-loved words for calming your soul. They are also beneficial in preparing your thought for the Silence.
