All mind-body practices, including other forms of yoga and meditation, have an effect on the brain. Learning about the brain is the best way to move your practice out of the class and into your life. If you practice yoga only as physical exercise, you are not really tapping into its full potential. Approaching your practice as exercise may help you relax for a short while, but wouldn't you like to carry peace into all areas of your life? That is why we study the brain so intensely in the deeper levels of this practice. By learning to become the master of your brain, you become the master of your life.
