We generate three karmic forces every day of our lives: thought, emotion, and action. The most powerful of these three is thought. Thought is the origin of action and controls emotion. It is as powerful a force as electricity. Like all forms of energy, thought can be used for both good and ill, just as electricity can be used to improve the quality of life or to destroy it. Since the action of every force has an equal and opposite reaction, and since thought is a power we all control to some degree, it is important to know just what thought is and how it can be used effectively.
