Swords map to air. Air is invisible, fast, and gets in everywhere — which in a person is thought, language, judgement, and the part of the mind that won't switch off. A sword is a tool and a weapon: it cuts through confusion, and it wounds, yourself included.
That's why Swords are the suit with the most painful pictures. Ace to ten walks the road of the mind — insight, stalemate, heartbreak, rest, winning and losing at once, leaving, scheming, self-imprisonment, dread, an ending. Most of that pain isn't something happening outside; it's your thinking about the thing that hurts.
Running well, Swords are your clearest part: seeing through, saying it accurately, deciding. Stuck, air's problem is circling — the same thought turning, assumption treated as fact, words used to sever. So when Swords appear, separate two things first: what actually happened, and what you think happened. Most of the suit's suffering lives in the gap.
