10. For in this way only may men have communion with the gods, for the gods cannot help man without the help of man.
I love the part in italics. It's similar to the oft-repeated but little-followed 'God helps those who help themselves'. We have to give of ourselves and put in the effort, not just make the gestures. For example, I could read a book, follow the steps, and put together a ritual, and say to myself 'hey, look at me, I did a ritual, so now I should get something back'... but if I don't understand why I've done the ritual, what the purpose of the ritual is, and if I don't properly prepare myself (see Old Laws 6-9), if I'm just following steps, I'll get back exactly what I put in, which is not a heck of a lot. Going back to the music example (because I think it's one a lot of people can relate to and it's certainly one that's working for me)... You can have a player who is technically proficient. That player can hit every note, do the music exactly as written in the score, and put on a 'flawless' performance. But... the performance would still not be complete. You could have another player, who is not 'technically perfect', maybe hits a note off by a little or misses a beat or two... but still be a much more complete experience because they are playing with emotion and energy and they are giving of themselves to the music. Of course, someone who is technically just awful, misses more than half the notes and is off key, well, they can put in all the emotion they want, if they do not understand the purpose and the form of the music, their performance will also be incomplete. I feel that what the Ardanes are telling us here is that you must be able to prepare properly as far as the steps of a ritual go - AND also put the emotion/energy/power into it. Otherwise it's just mechanical.
Of course what I 'feel' is quite likely in need of refinement - so, am I at least in the ballpark?

P.S. I don't think if I put all the energy in the world into a well-thought-out ritual to bring myself money that I'm suddenly going to win the lottery; I would imagine that Deity is a lot more subtle than that

I think it would mean I'd find a way to save myself some money; or maybe that creative idea would go from nebulous thought to an opportunity I hadn't considered.
