of United Arts, the International painter's association "Cor Ardens" (Flaming Hearts), and the International Art Centre "Corona Mundi" ("Crown of the World"). In December 1923, Roerich, along with her family, moved to India. This country had always been of great interest to the Roerichs. Adoration of India and its spiritual culture was not unusual among some Russian intellectuals of the time, feeling that their moral searches coincided with Indian spiritual tradition. From 1924 to 1928, Roerich took part in a Central-Asian expedition organized by N. K. Roerich, that traveled through hard-to-reach and little-investigated regions of India, China, Russia-Altai, Mongolia and Tibet. During the expedition, research in topics such as history, archeology, ethnography, history of philosophy, arts and religions, and geography was conducted. Previously unknown mountain peaks and passes were mapped, rare manuscripts were found, and rich linguistic materials were collected. Special attention was paid to revealing the historical unity of cultures of various peoples. The expedition was carried out in very difficult conditions. Roerich shared all hardships of the travel with the others: hard passages, robber's attacks, and obstacles created by English officials that nearly resulted in death of the expedition. In April 1925. when N. Roerich's expedition stayed in Gulmarg, Roerich began to translate an extensive selection from Blavatsky's "Mahatma's Letters" from English to Russian, which she published in London in 1923. She also wrote a book named "Chalice of the East", which was published that year under the pen name "Iskander Khanum". Roerich's manuscript "Foundations of Buddhism" was published in 1926, at Urga (now Ulan-Bator), where her expedition was staying at the time. In this book, the fundamental philosophical notions of Buddha's Teaching were interpreted. The book also spoke about the moral basis of this Teaching and helped sparkng interest in Buddhism in the west. In 1927, one of the Living Ethics books ("Community") was published in the same place in Mongolia. After finishing of Central-Asian expedition, Roerichs remained in India, in Kullu valley Himachal Pradesh. There, in 1928, they had found an Institute of Himalayan Studies "Urusvati" (this means "Light of Morning Star" in Sanskrit). It was planned as institute for complex study of Asian regions which exerted influence on the development of world culture. Among the tasks of "Urusvati" was the complex study of human, its psychic and physiological features. Roerich became an Honorary President-Founder of the institute and actively took part in organization of its
