The name itself, however, was reported as early as the 17th century, by way of Estêvão Cacella, the Portuguese missionary who had heard about Shambhala (transcribed as Xembala), and thought it was another name for Cathay or China. Cacella in 1627 headed to Tashilhunpo, the seat of the Panchen Lama and, discovering his mistake, returned to India. The Hungarian scholar Sándor Kőrösi Csoma, writing in 1833, provided the first geographic account of "a fabulous country in the north...situated between 45' and 50' north latitude". Theosophy During the late 19th century, Theosophical Society co-founder Helena Blavatsky alluded to the Shambhala myth. Blavatsky, who claimed to be in contact with a Great White Lodge of Himalayan Adepts, mentions Shambhala in several places, but without giving it especially great emphasis. Later esoteric writers further emphasized and elaborated on the concept of a hidden land inhabited by a hidden mystic brotherhood whose members labor for the good of humanity. Alice A.

They also believed that Belukha Mountain in the Altai Mountains was an entrance to Shambhala, a common belief in that region.

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.
