Air is, of course, related to the astrological air signs (Gemini, Libra, Aquarius), and has a lot of the same traits – Like actual Air itself, the Air signs hold strong traits of action, ideas, and movement. They are the “winds of change.” Invisible to the eye, but if a gust of air energy is directed at you, you move. This might imply that you’re feeling a bit “up in the air” rather than grounded and secure.
The actual definition of this specific card in the Cartouche is a little different to the air signs. It speaks of intellect, travel, communication, and speed. There’s a strong link with commerce here, as well. So if you’ve chosen Air to represent your Root Chakra, it’s likely that one or more of these traits are important parts of what make you feel secure.
