I had a strong interest in peak performance physically and mentally as it relates to being a warrior, but the interest now is more in peak performance for life in general. Over the years the Special Operations community has explored these topics, but disappointedly never really embraced as part of our culture. However, there is interest now in using mediation to address PTSD.

The two most recent books I read are:

Altered Traits: Science Reveals How Meditation Changes Your Mind, Brain, and Body

Why Buddhism is True: The Science and Philosophy of Meditation and Enlightenment

The first book provided some interesting insights on the how scientific research is evolving, how the tests are conducted, the associated bias that is difficult to eliminate, etc. However, it provided less than a chapter in total on how mediation is proven to change your mind, brain, and body. Frankly, there isn't sufficient scientific evidence yet, but according to the authors that is changing based on the large volume of ongoing research.

The second book I enjoyed much more. The author draws parallels in the latest views from the world of psychology and how they align with what Buddhists have discover centuries ago.

The author does a good job of explaining some the key tenants of Buddhism in plain English, such as mindfulness, emptiness, and nirvana. While in plain English, the concepts are not simple and the author doesn't simplify them. If you're interested in the topic, I would recommend this book.
