Paranormal Communism - From the Biography of Gleb Bokii (1879–1937), the chief Bolshevik cryptographer and one of the bosses of the Soviet secret police:
"Inspired by Theosophical lore and several visiting Mongol lamas, Bokii along with his writer friend Alexander Barchenko, embarked on a quest for Shambhala, in an attempt to merge Kalachakra-tantra and ideas of Communism in the 1920s. Among other things, in a secret laboratory affiliated with the secret police, Bokii and Barchenko experimented with Buddhist spiritual techniques to try to find a key for engineering perfect communist human beings. They contemplated a special expedition to Inner Asia to retrieve the wisdom of Shambhala – the project fell through as a result of intrigues within the Soviet intelligence service, as well as rival efforts of the Soviet Foreign Commissariat that sent its own expedition to Tibet in 1924."
