As an emotional processing tool, I often will write letters that I never send. And I am always amazed at how the exercise moves me. Sometimes the person the letter is directed to will later come to me and interact with me in a way that seems like they got my unsent letter. It's as if that unspoken conversation took place in the ether and we are now living in its shone light. I cannot explain. I don't try to. I just marvel at it when it happens and smile.
Perhaps that is what prayer is for people. A series of unsent letters from one person's heart into the ether to an unnamed recipient, in the hopes that someone, somewhere will respond. I think we all, at one time or another, send out letters into the universe. Whether we call it prayer, or hope, or dreams, it matters not. I think it allows us to speak from the deepest recesses of our heart and feel like we've been heard.
