"هكذا تكلم زرادشت" (Thus Spoke Zarathustra) is a philosophical novel written by the German philosopher Friedrich Nietzsche. Published in the late 19th century, it presents the teachings of Zarathustra, a prophet-like figure who shares his insights on morality, religion, and the nature of existence. The book is structured as a series of poetic discourses and parables. The central themes of the work include the concept of the Übermensch (Overman), the critique of traditional morality, and the idea of eternal recurrence. Nietzsche uses Zarathustra's journey to explore the transformation of human values and the pursuit of individual greatness, challenging readers to rethink their beliefs and embrace their potential.
