Not having read the book I can't give first hand testimony on its contents, but I have been paying attention to the debate between its advocates and critics. Those who voice concerns have said that The Secret (essentially) places blame for life's negative occurrences squarely in the lap of the individual (i.e., "It's your fault you got cancer/become the victim of a violent crimes/ lost your jobs and home/etc., by virtue of your negative thought processes.") Which in my humble opinion, could be sufficient reason for concern when considering the fragile emotional/psychological states of individuals most likely to be drawn in by such outlandish promises.
