First, if you're trying to command and bind any spirit, from my perspective, you're going about things the wrong way. Even if you're doing an exorcism, the goal isn't to bind the spirit but to unbind the person who's obsessed or possessed, and send the spirit on its way.
Second, if you're trying to change the world so you don't have to change yourself, you're going about things the wrong way. Since we constantly co-create the world we inhabit, the most powerful and effective way to get the life you want is to change what you put out into the world so the world will respond to you in differently. Trying to get entities to do the work for you is wasting their time and your own.
