In modern Vodun and diaspora systems, a mirror box has a variety of uses. Basically, it is a box that has mirrors on the inside. The purposes of these depend on why they are there.
Mirrors, aside of being sacred to Oshun, and to some degree Boyuto, capture and reflect a person’s image. This captures and reflects Ashe in some cases, or aspects of a person’s Ori in others. It can also shield or amplify, as the mirror itself has its own Ashe and natural characteristics. Much like crystals, they can be given a purpose depending on their natural options.
Inside a box, it can shield the outside world from the box’s contents by reflecting the energy of the object inside back to itself. It can capture a person’s image while making a request or prayer in order to “program” objects such as crystals or nkisi. It can aid in imprinting a talisman housed in a box onto its possessor. It can also help to amplify the power of an object.
Mirrors in a mirror box are numbered and arranged according to their purpose for being there. Their shape is also relevant. Square or diamond shaped mirrors are generally used for protection, containment, and sometimes “hexing” when a curse is for justice or preventing someone from doing harmful things. Round mirrors are generally used for love and emotional issues, and also for radiating energy. Triangular mirrors or mirrors arranged in a triangular pattern are often used for fertility, charisma, and worldly power. Different people may have different ways of doing things, but these are generally the standard.
