General Book of the Tarot
By A. E. Thierens, 
Nine of Cups
Victory, success, advantage, gain, triumph, superiority, etc. “The heart’s content.” (Waite) Reversed, the card seems even better: Sincerity, truth, loyalty, good faith, frankness, ingenuity, opening the heart, liberty, familiarity, etc. Concord, contentment, physical well-being.
Many of the addictions are very suggestive of the influence of the Water on the house of the heart, the Fifth; and we can only say, that they are fairly exact and to the point. The card must signify the realisation of hopes and wishes lying in one’s own power or destiny, making one enjoy the fulness of life, and adopting the philosophy of Epicurus. There is no evil in it. It shows goodness and a jovial disposition, not only contentment and happiness in one’s self, but also, owing to Leo-influence, the love of bestowing hospitality on other people and helping them.
