Ace of Cups
Read to know yourself, not to surrender yourself: relate to the card; never obey it. These are what two traditions wrote, not predictions.
In Waite's words: The Pictorial Key to the Tarot (1911)
The waters are beneath, and thereon are water-lilies; the hand issues from the cloud, holding in its palm the cup, from which four streams are pouring; a dove, bearing in its bill a cross-marked Host, descends to place the Wafer in the Cup; the dew of water is falling on all sides. It is an intimation of that which may lie behind the Lesser Arcana.

Root of the Powers of Water
A WHITE Radiant Angelic Hand, issuing from clouds, and supporting on the palm thereof a cup, resembling that of the Stolistes.
From it rises a fountain of clear and glistening water: and sprays falling on all sides into clear calm water below, in which grow Lotuses and Water-lilies. The great Letter of the Supernal Mother is traced in the spray of the Fountain.
It symbolizes Fertility — productiveness, beauty, pleasure, happiness, etc.
