Short meaning: You feel regret over a relationship that went awry and long for it to be the way it was. The Six of Cups is the card of nostalgic feeling. You may be able to revive this relationship or heal rifts now because, with the benefit of hindsight, you see things more clearly.
In-depth meaning: The Six of Cups is a card of reflection and the Subject could, or should, be looking into their past to gain some clarity in the here and now. The Subject is likely to be thinking about a particular relationship, or person, wondering whether there is a chance of a reunion or a reconciliation of some sort.
Given that time has passed and people grow up, there is probably a chance that the things that went wrong in the past could now be put right. But, when considering resurrecting an old relationship, the Subject should be careful not to look at the past through rose-tinted spectacles. They need to be sure they do, truly, understand what the old issues were and that they can say, with confidence, that this relationship won’t follow the same path as before.
Notes on the image: There is blossom and leaves on the tree and all six Cups are securely held. This is to indicate hope that a relationship can flourish – this is likely to be a relationship with problems in the past which, with the benefit of hindsight and experience, can be saved, with a bright new future ahead if nurtured in the correct way.
