Authentism (Russian: Аутентизм), incorporated as the Tezaurus Spiritual Union (Духовный Союз "Тезаурус"), is a Rodnover spiritual philosophy and psychological order created by the psychologist Sergey Petrovich Semenov in 1984, in Saint Petersburg. The movement is based on the teachings of the "Russian Veda", considered an expression of Slavic paganism, Russian cosmism and psychoanalysis. The aim of the Authentist philosophical practice is to reveal one's own true spiritual essence, which is identical with God, Rod—which is viewed as the complementary unity of Belobog/Sventovid and Chernobog/Veles—and therefore the unity of mankind and God, which characterises Russia's special mission opposed to Western individualism.
