I usually read the 6 of Swords as weariness. In my deck the person being carried by the swan feels like a period of quiet reflection and gentle rest before a fresh start. 🦢
For some reason I always link it to the 5 of Swords — that one’s about hostility, fights, disputes. The 6 can come after the battle, showing the tiredness or sense of defeat that follows. Other cards nearby can change that flavor, of course. 😴
Compare it to the 4 of Swords, which is rest too but more inward, like pausing to catch your breath before you jump back in. The 6 leans toward total exhaustion.
Hope that was clear! 😊
