The red book

In 1913, at the age of thirty-eight, Jung suffered a bitter experience of "confrontation with the unconscious." He saw images and heard voices. He was worried about the possibility of developing schizophrenia. He wrote everything he saw and heard in a book with a red cover, which he later called the Red Book. Writing this book extended for sixteen years, which Jung lived in solitude. Jung considered that this period was a special and valuable time in his life and it influenced his way of thinking. After Jung's death, his family kept this book in a Swiss bank, and the book remained hidden from researchers and readers until his family agreed to publish it in 2009, after the writer Sonu Shamdasani tried to persuade the family to publish the book. The book was published at the end of 2009 in both German and English, attracting thousands to buy it, and it is considered a spiritual autobiography of Jung, in which Jung documented what he did not include in his published scientific works.
