In this "advanced course in Anthroposophy," Rudolf Steiner addresses a great question of our time: What is the role of evil in human development? He discusses the year 666, when three streams of time intersected--the familiar linear stream and two "lateral" streams--and the reoccurrence of the 666-year rhythm in history.

At the heart of this mystery is the being Sorat ("the beast"), who attempted to flood humanity with premature spiritual knowledge by inspiring the scholars of the ancient Academy of Gondishapur. Although that academy was responsible for saving Aristotle's works, Steiner explains that it also generated tremendous and dangerous gnostic wisdom, which eventually spread through Christian monasteries and inspired Western scientific thought. Its immediate negative impact, however, had to be counteracted by the Prophet Muhammad and the establishment of Islam.

In contrast to the 666-year rhythm in history, the 333-year rhythm is connected to the healing forces of the Golgotha Mystery. The year 333 is a central point in the post-Atlantean age, as well as a pivotal moment in establishing the Christ Impulse and the new equilibrium it has brought to humanity, allowing people to gain wisdom through their own efforts. Such wisdom enables insight into three key areas: suprasensory knowledge of birth and death; understanding an individual's life; and the conscious ability to confront the adversarial beings, Lucifer and Ahriman.

Steiner also addresses a host of other themes, including occult Freemasonry in Anglo-American countries; materialism in the Roman Catholic Church; prophetic and apocalyptic vision; dualism and fatalism in pre-Christian times; and the delusion of time and space.

Seeking to awake his listeners to the urgency of the tasks ahead, he urges people to enliven spiritual understanding with enthusiasm, fire, and warmth of heart.
