This is a collection of 18 lectures delivered in Paris, France by Rudolf Steiner in 1906 is a must for any serious student of Steiner's philosophy. Ranging from esoteric insights into Christianity and Yoga, to astral planes and apocalypses. In his own words he says "Occult truths are beginning to be disclosed to the public. In a matter of twenty years or so, a certain number of them will already be common knowledge. Why is this? The reason is that humanity is entering upon a new phase which it is the object of this lecture to explain."
