The Hanged Man can be interpreted in two very different ways. All change is a small kind of death, as the old must die to create the new, and it may simply indicate upheaval or change in your future, perhaps beyond your control, but more likely a decision that, for good or ill, you will not be able to turn back from. The other interpretation is one of sacrifice, although whether this sacrifice is small or great may not be easily interpreted. Both interpretations imply permanence, and that you should give very careful thought to the decisions in your life.
