What flows through your mind sculpts your brain. Thus, you can use your mind to change your brain for the better—which will benefit your whole being, and every other person whose life you touch.

In Buddha’s Brain Drs. Hanson (a neuropsychologist) and Mendius (a neurologist) correlate modern concepts in neurosciences with ancient meditative practices. In an accessible yet satisfying style they argue that meditative practice helps higher frontal lobe based centers of thought and emotional control “fire together and wire together”.
The concentration that you gain from meditation takes the spotlight of attention and turns it into a laser beam. Concentration is the natural ally of insight, as you can see in this traditional Buddhist metaphor: We find ourselves in a forest of ignorance and need a sharp machete to clear a path to liberating understanding; insight makes the blade sharp and concentration gives it power.
