Secret Tibet, a 1943 Nazi film depicting the work in Tibet of three Nazi scientists, including Dr Bruno Berger, mentioned in Note 1 below. Hitler believed that the remoteness and inaccessibility of Tibet had protected the “racial purity” of the Tibetan people, and wanted to use the “scientific” studies of Berger and others to prove his theories on race. The Nazi swastika is a religious symbol of Buddhism and is found at Buddhist sites throughout India and China, including Tibet.
