Health realization (HR) is a resiliency approach to personal and community psychology first developed in the 1980s by Roger C. Mills and George Pransky, and based on ideas and insights these psychologists elaborated from attending the lectures of philosopher and author Sydney Banks. HR first became known for its application in economically and socially marginalized communities living in highly stressful circumstances (see Community Applications below). HR focuses on the nature of thought and how it affects one's experience of the world. Students of HR are taught that they can change how they react to their circumstances by becoming aware that they are creating their own experience as they respond to their thoughts, and by connecting to their "innate health" and "inner wisdom." HR also goes under the earlier name of "Psychology of Mind" and most recently "Three Principles" understanding.

"Consciousness" is likened to the light from the projector that throws the images onto the screen, making them appear real. According to HR, people experience their reality and their circumstances through the constant filter of their thoughts. Consciousness makes that filtered reality seem "the way it really is." People react to it as if this were true. But, when their thinking changes, reality seems different and their reactions change. Thus, according to HR, people are constantly creating their own experience of reality via their thinking. People tend to experience their reality as stressful, according to HR, when they are having insecure or negative thoughts. But HR suggests that such thoughts do not have to be taken seriously. When one chooses to take them more lightly, according to HR, the mind quiets down and positive feelings emerge spontaneously. Thus, HR also teaches that people have health and well-being already within them (in HR this is known as "innate health"), ready to emerge as soon as
