Roerichism
Roerichism or Rerikhism (Russian: Рерихи́зм, Рерихиа́нство, Ре́риховское движе́ние) is a spiritual, cultural and social movement that emerged in the United States in the first half of the twentieth century, though it has been described as a "thoroughly Russian new religious movement", due to its close connection with Russia. The movement centers on the Neo-Theosophical religious doctrine of Agni Yoga, or the Living Ethics, transmitted by Helena Roerich and Nicholas Roerich.
