Psychology is its characteristics, theory of understanding and interpreting its behavior, and some of the disorders it may encounter in its life. The interpretation of the reasons and motives for its behavior is limited to a female, as she is a female, and only a female like her can understand a female. The book attempts to develop a psychological theory specific to the female, with the aim of reducing the errors that can be used to interpret its behavior. It was a difficult task, as most of what has been written about the female has been written by men, and therefore has sometimes been misunderstood. The book is a serious attempt to appreciate the female's feelings and respect her decisions, plans, and feelings in order to put them in the appropriate context. A deep understanding of it will lead to the restoration of half of society to a level of understanding, thinking, and planning. Read the book without prejudice; you will find it a gentle and delicious treatment that leads to respecting and appreciating the female with the appreciation she deserves.
