The Mental Health Unit of this course is entirely Principle-based. Since the course is focused on health educators, this unit focuses on why it is important for young people to grasp the inside-out nature of thought, and the fact of Innate Health and resiliency as a "default setting" for people. Students in this unit learn how to present the basic information about mental health and mental illnesses from the point of view of the Principles. The unit includes a section on the Diagnostic and Statistical Manual (DSM) definitions of the most common thought disorders and explains them from the perspective of the Principles.
