GURDJIEFF'S PLAN WAS TO CREATE AN INSTITUTE to train "helper-instructors" who would then spread the teaching. He first tried to establish the Institute in Moscow but the Russian Revolution forced him to depart for Essentuki. Here he opened the Institute but the mass psychosis of the time forced him to leave for Tiflis. In Tiflis and later in Constantinople he again opened the Institute and closed it because of the harrowing conditions. In Europe he first hoped to open the Institute in Berlin and later in London before finally establishing it at the Château du Prieuré at Fontainebleau-en-Avon.
