I enjoyed reading this book - it is a mix of personal experience, and Tara Brach's client stories. At times the author is almost too honest, as she describes the times we all have when our behaviour falls short of what we would expect of ourselves.
The author is clearly very familiar with many Buddhist texts and stories, however there are no references given to the sources. An appendix of references and a bibliography would be a good addition to future editions.
The explanation of resistance is particularly good - this is a concept which I heard of before, but understand it better after having read this book.
The book is not perfect, and there is room for improvement - at risk of invoking the author's ire, I will list some suggestions here for improvements:
At times, the author's honesty even could cause doubts about the approach of using meditation to reach self-acceptance: is too much time spent on retreats, and trying to meditate, perhaps *not* the best way to live ?
A difficulty I have with the book, is the length and the structure. Also there is a great deal of name dropping, which can at times be irritating.
A more 'left brain' approach, with shorter and more direct methods of practising mindfulness, can be found in Padraig O Morain's "Light Mind: How Mindfulness Can Enhance Your Daily Life".
So perhaps if you are a left brainy type, then Padraig's book is worth a look.
