The Aces all represent the seed or germ, or single point of spiritual principal, from which all of the other cards of a suit are generated. They are potential – infinite potential.
In the suit of Disks, the Ace could represent a literal seed or germ, or anything with the potential to manifest as something in the physical material realm.
It strikes me that one of the central shapes on the card is that of a Shiva Lingam, the symbol of Divine Generative Energy.
Our experiences of material reality are waves of energy careening through space time, expressed as we experience them, based on a confluence of probabilities and expectations of consciousness, drawn from a set of nearly endless possibilities. The Ace of Disks is the point from which those waves have their genesis.
On this Earth Day 2021, may we choose our expectations wisely.
