The Kiblah, represents to the focal point of the magical current of a cult or religious system, the reservoir of magical energy which can be drawn upon by all who devote themselves to its Mysteries. Most religious systems include a similar concept. Christianity and Judaism have their Jerusalem or Mount Sinai, the Samaritans have their Mount Gerizim, Hinduism has its Mount Meru or Mount Kailasa, the Greeks had their Mount Olympus or the Omphalos at Delphi. Thelema has its Boleskine.
In the Thelemic system, the word "Kiblah" refers to the Stèle of Revealing, through which the Equinox of the Gods was revealed to our Prophet. The "abstruction," or replica, of the Stèle was originally housed at the manor of Boleskine and Abertarff, situated on the South-Eastern shore of Loch Ness in Scotland, 2 miles east of Foyers, 17 miles from Inverness. The manor, which was the Prophet's home at the time, is usually known simply as Boleskine, which is pronounced boll-ESS-kin.
