Ten of Cups
Upright
Contentment, repose of the entire heart; the perfection of that state; also perfection of human love and friendship; if with several picture-cards, a person who is taking charge of the Querent's interests; also the town, village or country inhabited by the Querent.
Reversed
Repose of the false heart, indignation, violence.
A. E. Waite, The Pictorial Key to the Tarot (1911), Part III §2The picture
Appearance of Cups in a rainbow; it is contemplated in wonder and ecstacy by a man and woman below, evidently husband and wife. His right arm is about her; his left is raised upward; she raises her right arm. The two children dancing near them have not observed the prodigy but are happy after their own manner. There is a home-scene beyond.
