Nicholas Roerich (October 9, 1874 – December 13, 1947) — also known as Nikolai Konstantinovich Rerikh — was a Russian painter, writer, archaeologist, theosophist, enlightener philosopher, and public figure.
In Hindu and Tibetan Buddhist traditions, Shambhala, also spelled Shambala or Shamballa or "Shambhallah", is a mythical kingdom. It is mentioned in various ancient texts, including the Kalacakra Tantra and the ancient Zhangzhung texts of western Tibet. The Bon scriptures speak of a closely related land called Tagzig Olmo Lung Ring.
Hindu texts such as the Vishnu Purana (4.24) mention the village Shambhala as the birthplace of Kalki, the final incarnation of Vishnu who will usher in a new Golden Age (Satya Yuga).
