The Hanged Man is one of the most passive cards inTarot. It indicates a period of time when everything stands still. The Hanged Man is also associated with sacrifice and martyrdom. The the Eight of Cups signifies dissatisfaction and we feel the desire to withdraw, to walk away from a situation, to change, as we hear the calling of a new or different future. In some cases the Eight of Cups can even indicate betrayal. The combination of the Hanged Man and the Eight of Cups is about letting go of someone or something that has been stagnant for too long.
To understand the elemental relationships between the cards, we should always take into account their actual meaning. The elements of the cards are Water (Hanged Man) and Water (Eight of Cups). The elements are neutral and rather friendly to each other, but they can lead to excessive passivity or inertia, not being able to make a move that would bring drastic change. With a high amount of water energy, a situation may need to reach a certain degree of emotional maturity, before it can be changed and transformed and that's exactly what the energy of the Eight of Cups will cause.
