THREE OF CUPS
This card refers to Binah in the suit of Water. This is the card of Demeter or Persephone. The Cups are pomegranates: they are filled bountifully to overflowing from a single lotus, arising from the dark calm sea characteristic of Binah. There is here the fulfillment of the Will of Love in abounding joy. It is the spiritual basis of fertility.
The card is referred to the influence of Mercury in Cancer; this carries further the above thesis. Mercury is the Will or Word of the All-Father; here its influence descends upon the most receptive of the Signs.
At the same time, the combination of these forms of energy brings in the possibility of somewhat mysterious ideas. Binah, the Great Sea, is the Moon in one aspect, but Saturn in another; and Mercury, besides being the Word or Will of the All-One, is the guide of the souls of the Dead. This card requires great subtlety of interpretation. The pomegranate was the fruit which Persephone ate in the realms of Pluto, thereby enabling him to hold her in the lower world, even after the most powerful influence had been brought to bear. The lesson seems to be that the good things of life, although enjoyed, should be distrusted.
