The internet is teaming with critics, and though Laura would call these people "psychopaths" and "organic portals", their criticisms are legitimate and rarely focus on attacking her specific teachings, and more on the things that she has personally done (such as allegedly scamming people out of their money in a fake house raffle, among other things). You can look these things up easily for yourself. Yes I know that this is a review of her book, but the point is that I don't want a person like that trying to teach me things about "truth."
Every spiritual teacher will probably have critics and naysayers, but when those critics can actually point to shady and even almost cult-like behavior, then the red flag should go up for anyone. When I looked into Laura I secretly wanted to find nothing bad, or at least not as bad as I found, because much of what was in the book WAS good and did ring true for me.
