Yoga is reputed to improve our physical and mental health, and to help us become more productive at work, more caring in relationships, and a more responsible contributor to society and inhabitant on this planet.

If yoga does accomplish all that—and most practitioners will swear it’s true—how exactly does it do it? Believe it or not, there are answers.

And they are based in how the human body/mind functions, how we are built and wired, and how what we do can direct and change that. Drawing on modern neuroscience, ancient wisdom, and decades of practice and teaching, Eddie Stern’s One Simple Thing explains how what we do affects who we become, and reveals how a steady routine of physical movements, activities, and attitudes are able to transform not just our bodies but our brain functions and emotions, and how we experience life.
