Harmony and past associations have brought present relationships. A sense of the past. Happiness that results from past efforts. Pleasant memories and the realization of a dream. Can also indicate new elements entering one's life which are linked to the past, which will work through the present to create the future.
In the film Parenthood there is a scene in which all the members of a large family come together to witness a birth. As the camera moves from person to person, we see as if for the first time the uniqueness of each one. The people talk and laugh, but suddenly their actions seem anything but ordinary. There is a sweetness in the air that builds until we see its very embodiment - the new baby.
It is a truism that there is violence, anger and mean-spiritedness in the world. Certainly there is enough of this, but there is also much good will and caring. A mother hands a drink to her child. A friend lends his car for the weekend. A worker fills in for a sick colleague. Small gestures, barely noticed, but so important. The Six of Cups is a card of simple goodness. It encourages you to be kind, generous and forgiving.
The Six of Cups also represents innocence - a word with many shades of meaning. You can be innocent in the strictly legal sense of lack of guilt. You can be innocent of the truth - unaware of some secret. You can be lacking in deceit or corruption - innocent of ulterior motive. Finally, you can be virtuous or chaste. These are all possibilities that can apply to the Six of Cups, depending on the situation.
Notice that the two figures on the Six of Cups appear to be children. Often this card represents a baby or young child. In a larger sense, it embraces all of childhood and the feelings we associate with youth (ideally!) - being carefree, playful, secure and loved. Children are our treasure, and the sweetness of the Six of Cups is a quality to be treasured as well.
