This card represents immense regret or disappointment; the horse’s head is bowed in sadness. But, its head is bowed away from the cups that still wait brightly above it, and away from the light at the top of the card. As this is a Cups card, this is a real and heartfelt emotion, not something that can be reasoned away, but nevertheless there is an implication that all is not lost – once you’re able to lift up your head again, you’ll see that. It’s not that there’s necessarily a choice (unlike the Ten of Swords), but this is just a reminder that what you’re experiencing right now won’t last.
It can be hard to let go of the past, of disappointment in oneself or in others; it can seem like a real physical weight. But there’s no weight to be seen here.
