Excerpt from Dark Days Tarot Guidebook by Emily Mundy:
Ace of Cups
The holy water in your cup overflows! Everyone and thing around you is replenished by an eternal essence that oozes from your pores, for you are basking in the culmination and abundance of plain happiness in your life. Your love cannot run dry; your personal, intimate relationships are so plentiful and uplifting that others share in the joy and contentment you’ve invited into your life. If the Ace of Cups is reversed, you may be disappointed in your relationships that are either unstable or unfitting. Honesty and open communication are needed in expressing feelings to those that are near you. Refill positivity in yourself before attending to the happiness of others.
upright: an abundance of joy; deep contentment
right: fertility; happiness on the horizon
