I am trained as a "hard science" PhD in Pharmacology and do understand scientific method. The LOA is not based on scientific method and the erroneous conclusions in metaphysics are based on incorrect scientific assumptions. These assumptions may have seemed reasonable in the 1800s that there was no air around us, only ether and that thoughts only transmit through ether. Perhaps this assumption is correct, however we are not surrounded by ether.

Law Of Attraction-Keep Seeing A Certain Person

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.
Although not concrete evidence that thoughts are capable of manifesting desires or even being capable of travel in waves through space and time, the messages within literally all religious literature still give plenty of food for thought. Even buddhism constantly stresses the importance of right thinking due to the fact that thoughts create reality as you can see by these 2 quotes:

The Law Of Attraction Manifestation

Look. Yes, you should have a vision of what you want your life to look like. I have a very clear vision. But it’s not hanging over my head. It’s in my pocket. Actually, it’s in my phone. And it changes as I change. They are a list of wants and goals but not needs. They do not define me or my worth. My vision acts as a compass. Do I want these things? Fuck yes I want these things. Will I not allow myself to be happy if I don’t obtain them? Nope. Been there, done that. Never again.
