From CGI's Paralemptor:

What can I say about Ouspenski except that he was way ahead of his time in understanding Dimensions, consciousness and some of the occult.

Para

Pyotr Demianovich Ouspenskii (known in English as Peter D. Ouspensky, Пётр Демья́нович Успе́нский; 5 March 1878 – 2 October 1947),[1] was a Russian mathematician and esotericist

Ouspensky's lectures in London were attended by such literary figures as Aldous Huxley, T. S. Eliot, Gerald Heard and other writers, journalists and doctors. His influence on the literary scene of the 1920s and 1930s as well as on the Russian avant-garde was immense but still very little known.[12] It was said of Ouspensky that, though nonreligious, he had one prayer: not to become famous during his lifetime.
