During the 1930s Krishnamurti spoke in Europe, Latin America, India, Australia and the United States. In 1938 he met Aldous Huxley. The two began a close friendship which endured for many years. They held common concerns about the imminent conflict in Europe which they viewed as the outcome of the pernicious influence of nationalism. Krishnamurti's stance on World War II was often construed as pacifism and even subversion during a time of patriotic fervor in the United States and for a time he came under the surveillance of the FBI. He did not speak publicly for a period of about four years (between 1940 and 1944). During this time he lived and worked at "Arya Vihara", which during the war operated as a largely self-sustaining farm, with its surplus goods donated for relief efforts in Europe. Of the years spent in Ojai during the war he later said: "I think it was a period of no challenge, no demand, no outgoing. I think it was a kind of everything held in; and when I left Ojai it all burst."
