Esoteric knowledge
From open-encyclopedia.com - the free encyclopedia.
sv:Esoterisk Esoteric knowledge is knowledge which is believed to be true but not generally known or widely accepted.
Historically, esoteric knowledge is not generally known in large part because it is deliberately kept secret from those outside a select group. Such knowledge was confined within certain disciplines, such as magic and freemasonry. This is not the case any more as most groups, such as the Theosophical Society, teach freely to anyone, often without cost.
