The book is dedicated to midlife and what is today called the “midlife crisis.” During this period, there is a transition from one psychological identity to another, a crisis of the spirit arises, and in this crisis old selves are lost and new ones arise. It is this internal activity and the meaning of this transition that the author explores. Taking as his source material the psychological events that occur in midlife, he does not ignore the serious interpersonal and social consequences of these important events that arise in the spiritual depths of the individual. In this book, the author does not offer solutions to the midlife crisis and does not give any specific recipes . He only recommends the path of entering the sphere of action of the psyche and passing through it. The book will be of interest not only to specialist psychologists, but also to a wide range of readers who will have or have already had to go through this difficult period.
