Here's why I simply don't buy the whole idea of the secret: there nothing presented that counts as any sort of evidence for the claims it makes.
It proposes a new law of the universe, "the law of attraction", that seems to mean whatever you think on and wish for is given to you by the universe, whether you believe this law or not.
If that isn't incredible enough, it goes on to explain some specifics.
- First that the universe for some reason will not grant a wish for something not to happen, it only understands such a wish as being a wish for it to happen. So if you wish to not get foreclosed for instance, the universe only hears "foreclose" and will grant you that wish.
- Second that it IS able to understand quantities. So it can understand a wish for $5 million dollars. Presumably that means if you wish to NOT receive $5 million dollars then it only hears the $5 million dollars and will grant you that.
Why the universe has such selective comprehension is not explained. Neither is how a universe can be conscious, how it can read your thoughts, why it would want to, how it can grant a wish, how it could ever resolve mutually exclusive wishes, and so on.
The bottom line is that what is conspicuous by its absence is any supporting evidence for the claims it makes. Wanting something to be true doesn't make it true. It's movie of pure speculation and wishful thinking.
Whether the "law of attraction" is a useful metaphor as opposed to whether it is literally true is another question.......
