A novel set between the cities and forests of Brazil, between civilization and nature, between the inner hero and the outside world. Its protagonist is a man of strong will who has dedicated his life to serving the indigenous people, and its essence is a return to the original source, the source of innocence, passion, and love. What is a human being if their innocence is lost on the altar of materialism? What is a human being if they lose their way to love? The Brazilian writer José Mauro concludes his Zessa Quartet by answering this question, leaving us his testament in the Confessions of the Monk Yaqtin. Perhaps one day we will realize that we may win the world and possess it, but we lose ourselves without love. What loss do you gain, O beast?
