Law of attraction practiced prior to the 1800s. If you are referring to arcane practices in Babylon and Biblical times that we have little knowledge of, I am aware and have looked at these. If there are some specific and relevant references I would be interested in hearing them. As you believe in a LOA, most of what you hear will be filtered through this lens. As I now do not, most of what I hear will be seen through that lens.
Arielle: One of the most common reasons is that after a few bad relationships some people unconsciously shut down and give up. They no longer believe the right person is out there for them and while one part of them is saying “YES, I want a relationship,” the other part is saying “NO! I’m afraid to get hurt again.” A big part of manifesting love is preparing yourself by overcoming the emotional wounds and baggage that we all have.
As a mind-reader, you should try to ATTRACT a different job, since in no way do I have any anger towards anyone with erroneous beliefs. I do feel sorry for you, but this is not anger. This is a free country and free society and you are free to believe anything you desire and free to waste your time as you see fit. You can smoke cigarettes as well. They will harm you and that is your choice. Same as a belief in a LOA.
You claim that "positive thoughts always resulting in positive things" is not the basis of the LOA. In part you are correct. The foundational basis in science, as I alluded to in the article was that thought stuff particles travel through ether (not air) and interact with formless stuff to create whatever it is that you are thinking about. This was how "the law" started.
