I have seen it a couple of times. I think there are some principles that are true about it. I don't necessarily agree with all of it. But the power of the mind is pretty amazing. An example of this is that Its pretty amazing that some people get placebo medication and they get better because they think they are getting better.

One of the principles is meditating and thinking that good things are going to happen as opposed to thinking about negative thoughts. I think thats a healthy way of living whether you follow the secret or not.

For those who haven't seen it, The Secret = The law of attraction. That what you think and meditate on is what draws itself to you.
