Sacred mysteries are religious beliefs, rituals or practices which are kept secret from the general public. It refers to esoteric knowledge which usually requires a formal initiation and a gradient of higher levels of belief before the concealed knowledge is revealed. Although the term “mystery” is not often used in anthropology, access by initiation or rite of passage to otherwise secret beliefs is an extremely common feature of indigenous religions all over the world, and this is especially so for occult secret societies.
