By reading yesterday's blog, you may understand that Kether is the "Dark energy-Dark Matter" that really isn't understood by us. Kether, the Source of All, is not known to us objectively, but it's presence is subjectively understood as a movement within all that moves.
Again, the Aces are attributed to Kether and they represent the most pure forms of energy. Each is a specific type, and density of Energy that we call the Alchemical Elements.
THE ACE OF CUPS:
Is Kether in Briah, depicting the influence of Kether on the Mental Level. The Ace of Cups is the Root Powers of Water, an element used to symbolize the Consciousness and emotions (in combination with Fire) .
The Thoth Deck Version of this Card shows the wave action characteristic of physical water implying the activity that encloses and directs pure consciousness. As the Universe of Energy is woven out of waves of consciousness, ideas, if you will, thus the Web in the background. The Cup, is the Womb of Form, and emerges from the Lotus (Crown) implying the idea of Womb, the seed of the concept of conception. Thus, the Ace of Wands is the idea of Phallus and the Ace of Cups is the Idea of Womb. The Ace of Cups is derived from-Yoni Moon, as the Ace of Wands is from Phallus- Sun.. Thus we have the "Holy Grail",. Here the dark Sea of Binah supports the Two in One Lotuses that fill the cup with Life Fluid, be it symbolized, by water, wine or blood. Two in One, is the realization of the Womb and Phallus.
The Holy Spirit represents the All of Energy.
