“ A lot of self-help methods are based on mental discipline or on working through emotional issues. What these approaches lack in an awareness of how the body is an integral part of the equation. The health of your body influences what you experience in your mind. There is no split. If you can engage your whole spirit in the pursuit of fitness--not just your intellect, not just your emotions-- but instead everything inside you that is truly you, you'll discover what it is to be a whole person. ”
