Rudolf Steiner's Road to Self Knowledge consists of eight 'meditations' or spiritual-guides. The eight topics explored are: The Physical Body, The Etheric Body, Clairvoyant Cognition of the Elemental World, The Guardian of the Threshold, The Astral Body, The Ego Body or Thought Body, The Character of Experience in the Supersensible Worlds and The Way in Which Man Beholds His Repeated Earth Lives.
