As mentioned before, all of the Sixes in the Thoth deck may be considered to be auspicious cards, representing, as they do, Tiferet, the sefira of beauty, balance and integration. It is the first reflection of Kether (the Crown at the top of the Tree of Life).
In the RWS deck, this card depicts two children, playing together with cups of flowers in an idyllic setting.
The Six of Cups is representative of simple pleasures and pleasant memories.
May we enjoy them today.
