An Esoteric Cosmology presents Rudolf Steiner's early spiritual-scientific account of the evolution of the cosmos, the Earth, and humanity. Drawn from eighteen lectures given in Paris between May 25 and June 14, 1906, this work belongs among Steiner's fundamental introductions to Anthroposophy: a concentrated exploration of spiritual development, cosmic history, human evolution, reincarnation, supersensible knowledge, and the relationship between the human being and the universe. The Rudolf Steiner Archive notes that these lectures survive through notes by douard Schur and constitute the only known record of the course.
Steiner approaches cosmology not as material astronomy, but as an esoteric account of reality in which the human being, the Earth, and the cosmos unfold through spiritual stages of development. The lectures anticipate themes he would later expand in An Outline of Occult Science, making this book especially useful for readers seeking an accessible entry into Steiner's cosmological teaching, occult philosophy, spiritual evolution, Anthroposophy, and Western esotericism. For the Sublime line, this is best positioned as a serious metaphysical and spiritual text rather than as a general New Thought or self-help title.
