In his Karma lectures of 1924, Rudolf Steiner described earlier incarnations of historical personalities and significant experiences they had in the planetary spheres before their next birth. The author explores how these experiences manifest in subsequent birth charts and investigates possible striking similarities between the birth and death charts of successive incarnations. This is followed by similar investigations into the members of the first board of the General Anthroposophical Society, whose previous incarnations are considered certain. The book culminates in an examination of Rudolf Steiner's extraordinary individuality and his relationship with the masters of esoteric Christianity. 100 years after Rudolf Steiner's death, such insights can now be made public.
