Universal Spirituality and Human Physicality

Book excerpt: In this exceptional series of lectures, Rudolf Steiner speaks in scientific detail about the connection of the subtle aspects of human nature - our soul and spirit - to our physical constitution. At the heart of this course are the well-loved 'Bridge' lectures, which appear in English for the first time in their wider context. Steiner discusses the solid, fluid, air and warmth bodies, and how these are connected with the various ethers, the 'I' and human blood. He goes on to describe how ideals and ideas impact the various aspects of the human constitution - how morality is a source of 'world creativity' - with moral thinking imbuing life into substance and will.
