AstroPsychology is relatively a new subject. This is an effort to apply the wisdom of astrology to the new born modern psychology and develop a better understanding of human behaviour. What makes it a hot topic of discussion is its promise to be capable of bringing positive changes in human behaviour and personality. Astrology in itself is a very wide subject and can be applied to all faces of human life and even to all faces of life in general. Psychology, in the west, finds its roots in philosophy and metaphysics. But one may question if there was no system to understand the human mind and human behaviour for thousands of years. Didn’t our forefathers ever need to understand it? Or they never questioned how it was happening. Just thinking it logically would reveal that for sure there were systems to explain all of it and even cure the mental illnesses. The only difference was that they were not called psychology. Jung was one of those modern geniuses who saw it very early that there were many other ancient systems too that were equivalent to psychology and could explain the causes of human behaviour in one way or other. Astrology is a kind of psychology in itself and actually a lot more than that. It is the traditional system of understanding human personality in a very intense manner and it also addresses the relationship dynamics of a person with his parents, wife, children other family members and society at large. And not just dynamics but also the development and changes in these relationships from time to time. But then its name is astrology, so it also addresses thousand many more things about a human being than just what psychology is expected to do. The present book is the result of author's research spanning more than 4 years where the author tried to find awe inspiring correlation between astrology and human behavior. These findings were carefully noted and then verified again and again. As an author I don't claim this book to be the final word on AstroPsychology, or this book to be a complete work, but I sincerely hope that this book will inspire future researches and thoughts in scientifically fertile minds in years to come.
