Mlle. Marie von Sivers, a Russian by birth, and of an unusually varied cosmopolitan education (she writes and speaks Russian, French, German, and English equally well), had herself also reached Theosophy by other roads, after long seeking for the truth which illumines all because it illumines the very depths of our own being. The extreme refinement of her aristocratic nature, at once modest and proud, her great and delicate sensitiveness, the extent and balance of her intelligence, her artistic and mental endowments, all made her wonderfully fitted for the part of an agent and an apostle. The Oriental theosophy had attracted and delighted her without altogether convincing her. The lectures of Dr. Steiner gave her the light which convinces by casting its beams on all sides, as from a transplendent centre. Independent and free, she, like many Russians in good society, sought for some ideal work to which she could devote all her energies. She had found it. Dr. Steiner having been appointed General Secretary of the German Section of the Theosophical Society, Mlle. Marie von Sivers became his assistant. From that time, in spreading the work throughout Germany and the adjacent countries, she displayed a real genius for organization, maintained with unwearied activity. As for Rudolf Steiner, he had already given ample proof of his profound thought and his eloquence. He knew himself, and he was master of himself. But such faith, such devotion must have increased his energy a hundredfold, and given wings to his words. His writings on esoteric questions followed one another in rapid succession.[4] [4] _Die Mystik, im Aufgange des neuzeitlichen Geisteslebens_ (1901); _Das Christentum als mystische Tatsache_ (1902); _Theosophie_ (1904). He is now preparing an important book, which will no doubt be his chief work, and which is to be called _Geheimwissenschaft_ (Occult Science).
