Some of the things are wonderfully simplified, but overall I didn't get what I needed, and that was a way to teach mindfulness as more than just nifty exercises taken from Buddhism, I was hoping for more. At the same time, some of their recommendations really do require explanations, such as their belief that we, for example, we should evade answering "overly intellectual" questions. I find this just preposterous. Whereas I understand that mindfulness is first and foremost an experiential thing and that any issues regarding its precise definition arise from this, but if someone pays for a course they should well expect teachers who have exceptional understanding of the practice, including - whatever that means for the authors - "intellectual" understanding. To make things worse, they don't really emphasize the importance of good practice for teachers. Yes they repeat endlessly that teachers must now how to do what they teach, but essential for the authors it boils down to being able to meditate 5 minutes longer than your students, which is just silly. My teacher spent years in a Buddhist monastery before daring to teach, and I only decided that it was time to teach after 8 years of daily practice. This is because mindfulness is not easy and because a lot of the issues and hindrances people face are something that teachers really need to deal with, and having personal experience is crucial. Also, there is a whole segment missing on other qualifications that teachers should have, such as at least basic knowledge of human psychology and more importantly psychopathology, because contrary to popular opinion, mindfulness is not for everyone and it is not without its "side-effects"; untrained teachers can actually do harm.
The book gets 3 stars because it does some good. It gives you a set of decent scripts for beginners, it provides detailed instructions and structure for each class that teachers can expand upon as they wish, and this is really useful. Another thing that I appreciated was a really simplified view of Buddhism which is sure to upset Buddhists but they do give those answers that you need for a class that is secular, so that's a plus as well.
