The Lake depicts the population of the world, every drop, a person. Two distinctly different channels of personality-"being" and "doing"-are blocked by the two dams, resulting in a mental illness, such as depression, schizophrenia or other psychosis. During a lifetime, we encounter people who fall into these categories and wonder how they got that way and what we can do about it. The authors created this book in the belief that everyone has a critical need for authentic, understandable information about mental illness and offer this book to enlighten you and enable you to discern between a mental illness and a personality defect. * * * * Virginia Schroeder Burnham served as a consultant in medical research to the Federal Government for the Senate, the National Institutes of Health and the Food and Drug Administration.
