Rudolf Joseph Lorenz Steiner (1861 - 1925) was an Austrian social reformer, philosopher, economist, architect, esotericist, and economist. He rose to celebrity during the latter part of the twentieth century as a literary critic and author of philosophical works, later founding a spiritual movement called anthroposophy which was heavily influenced by German theosophy and idealist philosophy. Originally published in 1930, this volume explains how different stages of material cognition and higher states of knowledge can be achieved through meditation, concentration exercises, and a connection to the spirit world. This fascinating book will appeal to those with an interest in spiritualism, and it is not to be missed by collectors of vintage spiritualist literature. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
