This card usually features a charioteer, a chariot, and two creatures. There are variances, though. Sometimes the charioteer holds the reins; sometimes he does not. Sometimes the chariot has wheels, and others, it does not. Sometimes the creatures are moving; in other images, they sit still.
Despite all of those possible symbolic representations, it is generally considered a card of progress, of moving forward, of movement. When this card comes up, I rely on the image to direct my interpretation.
In this card, from the Legacy of the Divine Tarot, there is obvious power and movement. The charioteer appears to have control of the two creatures (each with their own agenda, it seems!), but just barely.
A card of power, of having just really understood one’s power and desiring to use it full tilt and right away. A little on the job training never hurt anyone, right?
