Using an accessible question-and-answer format, this short but focused book tackles themes relating to the etheric - or life - realm. What is etheric technology? What are the impacts of radioactivity and atomic energy? How should we read apocalyptic symptoms in science and society? In a fascinating series of discussions Nick Thomas examines a range of concepts, including: the right and wrong ways to develop an etheric technology; spiritual events in the etheric realm; how the physical world works into the etheric world and vice versa; Rudolf Steiner's 'Strader machine'; the nature of truth and lies; attacks by the adversaries on forces of vitality; and humanity's crossing of the threshold to the spiritual world. His explanations and ideas help to evoke a living picture of a great struggle between forces of good and evil, with the future of humanity and the Earth at stake.
