The Hanged Man is one of the most mysterious cards in the tarot deck. It is simple, but complex. It attracts, but also disturbs. It contradicts itself in countless ways. The Hanged Man is unsettling because it symbolizes the action of paradox in our lives. A paradox is something that appears contradictory, and yet is true. The Hanged Man presents to us certain truths, but they are hidden in their opposites.The main lesson of the Hanged Man is that we "control" by letting go - we "win" by surrendering. The figure on Card 12 has made the ultimate surrender - to die on the cross of his own travails - yet he shines with the glory of divine understanding. He has sacrificed himself, but he emerges the victor. The Hanged Man also tells us that we can "move forward" by standing still. By suspending time, we can have all the time in the world.
In readings, the Hanged Man reminds us that the best approach to a problem is not always the most obvious. When we most want to force our will on someone, that is when we should release. When we most want to have our own way, that is when we should sacrifice. When we most want to act, that is when we should wait. The irony is that by making these contradictory moves, we find what we are looking for. (Source: Learn Tarot)
