The book brings together teachings, especially from the last four years of the philosopher Huberto Rohden's life. Through the philosopher's lessons, the messages of the Great Avatars are described. The author synthesizes the history of the avatars who have been here, intertwining the human passions of the characters with a well-structured narrative that marks one of the distinctive aspects of his style. Guilherme leads the reader to take an interest in the teachings of the Great Masters—Christ, Krishna, Buddha, Lao-Tzu, Hermes Trismegistus, Ptahhotep, Helena Blavatsky, Giordano Bruno, Saint Germain, Leonardo da Vinci, Albert Einstein, and Huberto Rohden—raising philosophical and metaphysical questions, unveiling myths, and deciphering enigmas. He seeks what is real, what is permanent within oneself, striving for self-realization as a human being, reaching a higher level of consciousness, and cultivating values, virtues, justice, and wisdom. The novelistic narrative largely unfolds in a monastery located in the mountains near Lisbon, shaping the actions of its characters in the 21st century. It emerges precisely in a period of crisis for humanity, fragmented by the ego’s individualistic ideal.
