Practicing Mindfulness: An Introduction to Meditation (book review)
It adds some detail to mindfulness, but isn’t a breakout.
I have understood the importance of meditation, mindfulness and especially in the Buddhist outlook and this definitely helps underscore that tradition of thought.
I firmly believe this is a good resource to those new with mindfulness and might give explanations in a way that makes more sense and perhaps is more accessible.
That being said, if you are already comfortable with the idea of mindfulness, you probably don’t need this book.
