Practice of deliberately introducing incorrect information into teachings, publications, or other data. For example, two symbols in a table of correspondences might be swapped, or the name of an entity misspelled. Only initiates into the group itself would be given the correct information. The full phrasing, “a blind to the uninitiated”, is generally contracted simply to “a blind” by modern occultists.
Lofty reasons for introducing blinds into material are sometimes given, such as “to protect people from knowledge they haven’t received the proper training to fully understand”, but in all truth, they most likely stem from a simple love of secrecy for its own sake.
The Golden Dawn may have actually started the practice of using blinds. If they didn’t start it, they certainly did much to popularize it in the occult, and especially Hermetic, community.
