Look at Tarot card layouts (also I Ching hexagrams, cast bones, etc.) as icons on the “desktop” (user interface with “reality”) of the person being read…a synchronicity…an array of symbols that “are” the person at a given moment in time…another way of telling their story. This chance set of icons can be re-arranged, resulting in changes in the person in the “real” world.
This kind of manipulation is a sort of Cinemorphic (re-write yourSELF) manipulation…an alternate reality game. i.e. don’t just use divination methods to “tell a fortune” or read someone “as they are” but also manipulate the oracle to change them.
Look at the Tarot as a semiotic web (like an organism with an intelligence?) which we can interact with…have a conversation with…talk to….cajole.
