The purpose of the I Ching or the tarot … is to help you get access to yourself, by providing ambiguity for you to interpret. And this quality of ambiguity is shared with nearly all forms of divination — cast artifacts, or entrails, or weather formations, or events such as the flight of birds, that one could choose either to see as “omens” or to ignore.  The very thing that makes these divination techniques seem so unscientific is what makes it possible for them to work.
