This book is for those who have creative experience, for those who have already partaken of its sweetness and bitterness. It is a warning: creativity is not always manna from heaven, it often becomes a punishment. Modern psychology describes creativity as a purely positive phenomenon, which it is certainly not. This book sums up my research of both positive and negative aspects of creativity. I hope it helps psychologists, philosophers, teachers and psychotherapists get a clearer picture of creative states of consciousness. This book is an attempt to make self-actualization more accessible. Theoretical description of psychological and phenomenological aspects of creative states of consciousness, as well as determination of the conditions of creativity in different kinds of activities is an urgent problem. The study of inner mechanisms, content and phenomenology of flow-like states of consciousness makes it possible to reveal their influence on human psyche. In practice, flow-like states of consciousness can be used in everyday human activity to increase its efficiency.
