The law of assumption is "a belief that the world does not depend on what is there, but more so the assumptions you form in your mind while looking at it. So your assumptions create your reality. If you assume something will be positive, it will likely go that way. If you assume something is going to be negative, chances are that is how your experience will turn out. In your mind, as you are assuming you are bringing those thoughts to reality."
The law of attraction is "the belief that positive or negative thoughts bring about positive or negative experiences in your life. An example could be that you filled yourself with positive thoughts, and due to that you are attracting positive experiences. The opposite would be filling yourself with negative thoughts which lead to a series of negative experiences."
They are bother very similar.
My question is I have seen many people say this works very well and makes them rich.
Disregarding whether or not that is true, are You allowed to use this in Judaism? Or would it basically be saying that you can get whatever you want without having to ask Hashem? Or could it be kishuf? Or Avodah Zarah? (etc.)
