Excerpt from Dark Days Tarot Guidebook by Emily Mundy:
Two of Cups
You are joined with another being in a strong bond. The love bestowed upon this union derives from a divine source that has blessed the two of you with a cosmic congruence. Connectedness courses through the veins of your conjoined lives as if you share the same celestial blood. If these lovers appear upside down or leftward, a delay may be occurring in the union or the sense of harmony has been slightly disrupted. The cards surrounding the Two of Cups indicate the crux of instability and enlighten you to certain areas that need more attention. They may also suggest new prospects to explore as a pair and point toward particular areas of blossoming within your partnership.
Suggested prompts:
upright: flourishing partnership; deeply in love
right: discovering things with and about someone else
left: awkward timing; delay in romantic momentum
reversed: disruption or disharmony in your relationship
