People living today have the same access to the original creators' texts online as people in 1880 had in printed books. It's exactly the same material. You're essentially arguing against yourself because asserting that no one knows for sure about it would have to apply to the people in 1880 as well. Your argument is an appeal to ignorance, which is a logical fallacy. The text in the creators' books is precisely the data he's referring to, a intellectual creation that has absolutely no scientific basis.
This is a great book. But it doesn't really get into "The Secret BEHIND The Secret" so-to-speak. "The Master Key System" by Charles F. Haanel still is, and will ALWAYS be, the greatest book on this subject that has ever existed. It is "one stop shopping" and explains it all in a very simple and easy-to-read book that is almost a hundred years old. This book was the third I got from Esther and Jerry Hicks, and was not a bad read for what I knew at the time. But "The Master Key System" was TRULY the life-transforming book I needed to read. And THAT was the one that changed my life. This one goes into WHAT The Law of Attraction can do. But not really HOW or WHY.
When I got so sick of being on top of everything that I stopped caring enough to obsess over each disease and symptom I had, stopped taking all my supplements, and stopped doing what felt good to my doctor, but bad for me…I started to attract actual solutions that could help me heal. (Note: Please do not stop taking your doctor’s advice. I am simply sharing my own experience). It was simply because I stopped making my whole life about “illness” and “problems.”
Years later, I learned the same about financial security. When you worry and focus on the “problem” or the lack of financial security, NOTHING good will come from it. Nothing. When I decided to literally focus on every little financial “win,” and get rid of fears around money, my financial situation turned right around. And faster than I thought it could too.

2. Builds a strong foundation:: The reason why Manifestation Magic works and has positive testimonials is because of the science behind it. You’re gently taken from a place of lack to a place of abundance. This is crucial. I’ve said it a thousand times it’s your beliefs that will help you manifest wealth into your life, and if you can change your beliefs you will change your actions and that’s the REAL SECRET.
Unfortunately, many of us have troubled relationships with the idea of wealth. It certainly has connotations of greed and vanity. In order to attract money, we need to banish these negative thought patterns. A key aspect of The Law of Attraction is this idea that positivity breeds positivity. Therefore, you can learn how to harness positive money habits easily with help from visualization tools and techniques.
Develop an unflappable belief. Very likely you haven’t manifested what you desire because deep down you don’t believe that it could be yours. This is absolutely common and there is nothing bad about it. Nevertheless, if you lack the belief that it can be yours then it CANNOT manifest. With your disbelief you block the manifestation. Let’s say that you have a clear vision with strong desire but you don’t believe that it could happen for you. Then what happens is like saying; ‘’Actually, I cannot have it. I don’t believe that it can be mine.” The Universe responds; “so be it”. Why don’t you believe that it can be yours? Dig deep within yourself to find out what you belief is and then work on changing it.
