As far as Elubatel goes, you really don't have to use his chant as part of the system, if he bothers you that much. It will work fine without him. You could also invoke Ebuhuel and Atuesuel (or all eight of the angels of omnipotence, for that matter) in the success chant to balance out his energies. They are compatible for this invocation.
NAP is a portable system, if you're worried about doing it at home. I have done it many times in my car while at the local park. You can also do it sitting on the toilet at work. Just be quick, before your legs fall asleep.
On that note, if you wanted to work on your issues with wealth, you could afford a larger house, so you can have a backyard or a tea/meditation room to do your rituals in. Just because you have money doesn't mean you are part of the "corrupt system."
Hahaha, I think I developed a rather adversarial relationship with money over the years, and that's something I'm sort of working on fixing. I am possessed by the idea as of late though that money as we know it may not be a thing for much longer, and this in part is what is driving this main working. I want to be able to perceive opportunities to get the things that we use money for, either with or without the use of the money itself, you know? Money often feels like a needless extra step to me, but again, I'm working on changing that established relationship.
I think this is actually probably a good opportunity to integrate Elubatel into the working...I'm not seeking money, I'm seeking perception. I'm not seeking traditional "success," but rather the ability to successfully intuit info. I feel like that should limit Elubatel's disruptiveness to my internal psychology, rather than creating a cascading series of unfortunate events that somehow teaches me an important life lesson about intuition. Hopefully this is a nice safeish way for the two of us to get to know each other a little better.
