Christopher Germer's The Mindful Path to Self-Compassion is flat-out one of the best books I've read on acceptance and mindfulness. These ideas will seem familiar to most who are in some recovery program, like AA, or who have a daily meditation practice.
Acceptance is the big idea behind AA but Germer shows us how to practice acceptance of ourselves in our time alone and in all of our affairs far better than anyone else I have come across. The result is something really helpful in opening us up to the life in front of our eyes.
I wish I had found this book years and years ago, but then, Germer would remind me that the only important time to practice acceptance is now and tomorrow and always. I'm planning to give this book to friends and members of our family, many of whom already are on to its wisdom but who will still find its ideas and practices fresh and inspiring.
