The concept of a hidden land
Shambhala teachings inspired numerous educational, artistic, and spiritual institutions, including Naropa University, Shambhala Training, Shambhala Sun, the Shambhala School, Shambhala Institute, and many others.
Tibet was largely closed to outsiders until very recently, and so what information was available about the tradition of Shambhala was haphazard at best. The first information that reached western civilization about Shambhala came from the Portuguese Catholic missionaries Joao Cabral and Estevao Cacella who had heard about Shambala and thought it was another name for China. In 1627 they headed to Tashilhunpo, the seat of the Panchen Lama and, discovering their mistake, returned to India.
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. There were numerous Tibetan expeditions to discover Shambhala, but all in vain.
