Through his lectures and his part in the discussions - they were held daily by the various speakers and ranged over almost every field of modern knowledge - I gradually realized that Rudolf Steiner was in possession of unique powers. Not only did he show himself fully at home in all these fields; he was able to connect them with each other, and with the nature and being of man, in such a way that an apparent chaos of unrelated details was wrought into a higher synthesis. Moreover, it became clear to me that one who could speak as he did about the stages of human consciousness past, present and future, must have full access to all of them at will, and be able to make each of them an object of exact observation. I saw a thinker who was himself sufficient proof that man can find within the resources of his own spirit the vantage-ground for the deed which I had dimly surmised, and by which alone true civilization could be saved. Through all these things I knew that I had found the teacher I had been seeking.
