The Two, of any card suit, represents the Word and the Will. Therefore, the 2 of Cups is the first manifestation in the Suit of Water which is called Love because of the mutual annihilation of the individual by the process of Union; when the Divine Feminine and the Divine Masculine Unite, there is no male or female present.. only the Divine Androgen exists. .
The Two of Cups represents Venus in Cancer. Cancer is known as the most receptive of Signs, as it it the House of the Moon, and in that sign Jupiter is exalted. There is a superficial friendship among these three planets ( in astrology, the Moon is seen as a planet).
In the Thoth Deck Two of Cups, the paired Dolphins (the important symbol of the "Royal Art" of alchemy) are intertwined, with the flowing of Love coming from the Great Lotus of the Goddess, into the twin Lotus below and overflowing into the Cups resting on a calm Venus-Green Sea. This is a purity of Love, that the brain is unable to conceive of or often understand, making such an absolute annihilation of the individual in the Overflowing Power of Unity, a wonder.
The Will, and the Word, united become Form. The Word being Logos, the source of all Vibration and The Will being Spirit, the Fertilizer of all idea into Form. This language may sound obtuse, but this is an invisible Force, that words cannot give form to so we must unite words in such away that they allude to the mystery, rather than literate identification. If you ever have experienced a self-annihilating love where the ego becomes lost in the Overflowing Sensation of Being One from the Union of Two.....you'll understand that you just can't "wrap" your brain around it. The common statement being." I am at a loss for words....." There seems to be some kind of heated fluid that is drowning all reason. Then, my friend, you have experience what the Two of Cups alludes to! However, being a purity, from another dimension of conscious energy, after time, it will pick up detritus from our "shipwrecked" brain, and slowly progress to a Four of Cups, as the suit develops. The Second Law of Thermodynamics comes into play, and "...All things proceed from order to disorder." and we slowly degrade the Mystery, with identify words of reason.
The Two of Cups, is also called the Lord of Love under Will. which is its true meaning where Will is Spirit and not some egoistic possession of the brain, as that is a minor will indeed. The 2 of Cups shows the harmony of the Universal Female and the Universal Male, radiating an intensity of joy and ecstasy that washes away any and all concern. It is The Love, that connects us all together as One, while the massive flow of this connectivity to All, flows through the Union of Two, may explain why it seems so overpowering to individual reason.
When this card is thrown for the querent, and depending on its position in the reading, and the dignity of the accompanying cards, it usually means, love, marriage, and pleasure, Some say, warm friendship, but that is a weak statement for such an overwhelming heat, so it's more like an intertwining, of harmony, mirth, subtlety, pleasure, and a sometime dash of folly that seems to bind us in mystery and sensation of a "deeply Warm" friendship that radiates from the galactic core. This is an ecstasy that only the True Union of the Feminine and the Masculine can produce.
If the Cards accompanying the Two of Cups are all ill defined, than this card represents, dissipation, waste and silly action..
Thank you for your interest and comments. May you live long and prosper!
