Because the Major Arcana represents the Fool’s Journey, or our journey here as Spirit in the human form, the Chariot is the last card in the Major Arcana that represents us in the developmental stage. This card marks the end of our development and signifies scope and potential. If we choose to move forward, then victory will be assured. Note, that because this is the end of the developmental stage, it does not mean that we cease to learn as shown through the rest of the Major Arcana.
The Sphinxes represent Osiris, Egyptian God of the Underworld, and also the God of regeneration, resurrection, and most important of all, transition. The Magician is the one that drives the Chariot. Notice that he does so through summoning his will through his wand.
The star canopy represents our connection to the Universe and reminds us that we are star dust. The two crescent moons are a reminder that we are influenced by that of the heavens. The mercurial wings signify communication and is the tool that the Magician will take with him on his journey.
Remember that when you are on the Chariot, you will be pulled around by wild forces. As you will need power to gain control, you must ask yourself: where am I sending my will? Wild forces will pull you around if you don’t know where you’re going.
