'That in our times a kind of supernumerary person is appearing who is egoless, who in reality is not a human being, is a terrible truth.' – Rudolf SteinerAre there people on earth today who do not have a self – a human ego or 'I'? The phenomenon of 'egolessness' – the absence of a human being's core – was discussed by the spiritual teacher Rudolf Steiner in lectures and personal conversations. An egoless individual, he intimated, is an empty sheath through which other spiritual entities could operate. Erdmuth J. Grosse brings together many little-known quotations from Rudolf Steiner's spiritual research and supports them with a wealth of disquieting reports, testimonies and examples from literature and politics. He places these insights within the broader context of the riddle of the human self, throwing light on the spiritual development of the individual and humanity as a whole.In this thought-provoking study, Grosse goes on to discuss the role of comets, the effects of cyanide on the human constitution – especially in the light of the Holocaust – and the hidden effects of ceremonial magic, occult lodges, cults and sects. In conclusion, he offers positive solutions to humanity's present predicament by describing the healing impulses of social threefolding, the invisible spiritual beings seeking to help humanity, the role of the gods, the Christ impulse and the true goals of human evolution.
