Every thought you have changes the energy in your body. When you have a happy thought, your energy expands and allows your energy to flow, creating strength. When you are sad or have irritating or angry thoughts, your energy contracts, reducing the flow of energy. To increase your health; keep happy thoughts flowing. 🙂 Try an experiment. Think of a happy thought and notice how you feel. Next, think of something that you don’t like and notice how you feel. You decide what nurtures you most and keep that thought.
