In response to these questions, Rudolf Steiner delivered the informal lectures in this book to the workers at the Goetheanum:
• What is the relationship between coming to see the secrets of the universe and one's own view of the world?
• How far must one go before finding the higher worlds on the path of natural science?
• Do cosmic forces influence all of humanity?
• What connection do plants have with the human being and the human body?
In answering these questions, Steiner covers a wide range of topics, from the development of independent thinking and the ability to think backward to the uses of what seems boring and the reversal of thinking between the physical and spiritual worlds, and from the "physiology" of dreams to living into nature and the spiritual dimension of various foods.
As always in his lectures to the workers, Steiner's style is clear, direct, and accessible.
