To enhance your level of wellness it is important to address all aspects of who you are and everything that is happening around you. Everything about you and your life is important and deserves to be taken care of. Remember that you are a whole, made up of interrelated parts. Your Physical, Mental, Emotional, and Spiritual aspects depend on one another for well-being. When one is disrupted, the others suffer as well. This concept is referred to as a whole person or holistic approach to healing.
