I only looked briefly at it and it looked like christian new age hodgepodge with little applicability.

I would guess from a first glance that the purpose is to prevent people gaining first hand experience of spirit interactions. If it's a psyop it makes sense to spread mindless preaching without actual bible study. That way you have people filling their heads with nonsense they can't use for anything. If the bible itself was pushed there'd be people who actually learned something so it seems reasonable to write some long complicated thing if you wanted to entangle them. It also makes them unable to learn since they now have an authority to follow and can't create anything of their own.
