The book "Wise Tales for Children and Adults" by coach and psychologist Marina Alyassova is one of the most unpretentious and most important books I have read. The main thing to know about this book is: the tales in it are for children, but the book is also for adults. And there is no contradiction in that. Marina Alyassova's book is in its own way a textbook of mental literacy.
At first glance, everything is really uncomplicated. It is a small collection of very kind stories about a five-year-old girl, Nastenka, and her mother, and each story is a conversation, where Nastenka asks a difficult question, and her mother shares with her daughter worldly wisdom. That's how many informative children's books are structured, isn't it?
