Rudolf Steiner, Lectures on General Anthroposophy
From AnthroWiki
The lecture cycles and individual lectures given by Rudolf Steiner from the beginning of the 20th century, first within the framework of the Theosophical Society and later for the members of the Anthroposophical Society founded in 1913 in Germany, Austria, Switzerland and many other European countries, form by far the most extensive part of his lecture work. These lectures are published in Rudolf Steiner's Collected Works in their chronological context.
