This book was not my "cup of tea." My book group will be discussing it soon, so I gave it a good try, reading about 2/3 of it. Because this is not a readily available book, my excuse for stopping was that I had to pass the copy along to another reader. To be truthful, I didn't care much about finishing it. The focus of the book is that when many people, at the same time, meditate/be thoughtful about a concern of wide importance, change can be brought about. This is too simplistic a summary, of course. The author presents scientific evidence that this can and does happen. It is rather fuzzy science. I am too much of a skeptic about this to be persuaded. The writing style is not easy to read, for me anyway. Long, complicated sentences make the reading dense for me. Subtle activism is too subtle for me.
