Many of us come to know the Law of Attraction concept after watching the popular movie,
The Secret. However, the concept isn't a completely new one. I believe a lot of us are familiar with the term "subconscious mind", which in essence manifest what we think about..
I still believe that the power of Law of Attraction and/or the subconscious mind, is the seed of all changes and the cause of many phenomenons in this world. There are several gurus out there who are teaching this, and I don't think it's hard to filter out the good ones. I like Bob Proctor, who is featured in the movie
The Secret. My reason may sound funny, but here it is: He is an old guy. I don't think a 70 something year old man like him would do this for any reason other than doing what he loves and doing what he thinks is meaningful. I would not believe he does it for the money only, and I do not believe he would do unrighteous things to promote his program.
Aother reason I like him is that I think he is more experienced in this field (again given his age.

) When you see him talk, you will see that he knows what he is talking about. I also know that he has been studying this for a long long time. He frequently talks about a book he owns since very young - Napolean Hill's
Think and Grow Rich, which is also the Law of Attraction in application.
If you want to see Bob Proctor's teaching, check out
The Science of Getting Rich Program, where he is featured with the
Chicken Soup for The Soul creator Jack Canfield, and another
Secret teacher Michael Beckwith.
