Beware my friend of the "cause and effect" materialistic trap! Prayer works, but its' more like talking to your inner id. All the programing is in place for it to work. My limited experiance seems to indicate that we are pre-programed to evolve when in a frame of mind to "pray".
That was my point too, but you said it much more eloquently, Carmel.
My daughter in law's mother is a radical fundamentalist and was preaching to me about prayer one time. I told her my experiences with positive thinking and goal setting. Her reply? "Isn't it wonderful. Jesus has a way to answer your prayers, even if you don't believe in prayer?" I wanted to hurl.
