Between 1905 and 1908, Hedin investigated the Central Iranian desert basins, the western highlands of Tibet and the Transhimalaya, which for a time was afterward called the Hedin Range. He visited the 9th Panchen Lama in the cloistered city of Tashilhunpo in Shigatse. Hedin was the first European to reach the Kailash region, including the sacred Lake Manasarovar and Mount Kailash, the midpoint of the earth according to Buddhist and Hindu mythology. The most important goal of the expedition was the search for the sources of the Indus and Brahmaputra Rivers, both of which Hedin found. From India, he returned via Japan and Russia to Stockholm.
