Shambhala is a mythical kingdom in both Hindu and Buddhist mythology, where the most sacred spiritual teachings are preserved. It is a Sanskrit word meaning "place of peace" or "place of silence". It is said to exist somewhere between the Himalayas and the Gobi Desert.
According to the Seventh Doctor, the capital city of the Silurians was known as Shambhala among some. (AUDIO: The Silurian Candidate [+]Loading...["The Silurian Candidate (audio story)"])
