I'm surprised this article didn't talk about brain wave states. I'm also surprised that it doesn't distinguish what could be described as anxious or panicked prayer -- the type uttered when you're scared, feeling threatened, or hoping to intercede with someone else's behavior that you think is dangerous or self-destructive -- versus what I'd call spiritual alignment prayer, which is functionally just another kind of meditation but one that is directed towards a deity of some kind.
My earliest intro to meditation was from Shinzen Young. I don't think his instructional tape has been converted to an MP3 file, but there are some videos for purchase on his website and on YouTube.
