This chakra is associated with Tarot trump number 10, The Wheel of Fortune.
The choice of Jupiter for this chakra is an interesting one. Traditionally, the third chakra is associated with the force of Will, and the ability to put oneself forth in the world. Jupiter is an expansive, beneficent force in astrology, so the “putting forth” part of the chakra is well represented by this planet. Jupiter is an optimistic force, and this optimism is needed if we are engage the world with any success.
Jupiter rules the sign of Sagittarius, an outward sign interested in exploring, higher education, and distant travel. Jupiter is also co-ruler of Pisces, another sign of expansion, but this time on the psychic and spiritual planes.
The metal of Jupiter is tin. This metal has a prime use in coating other metals as a protectant, as it does not oxidize easily. The Jupiter force is the outer, protective force we need as we put our third chakra into contact with others. Also, tin is related to lead on the periodic table of elements. This reminds us that the expansion of Jupiter needs to be rooted in the groundedness of Saturn, so that we don’t lose sight of reality (which can be a problem for the Piscean part of our temperament).
The note of Jupiter, and the third chakra, is A#, the highest pitch of the planetary scale. Jupiter is certainly the loftiest of planetary forces from the standpoint of optimism and engagement with others. It helps us keep our chins up when the chips are down. As you may know, the word “jovial” comes from the Roman god Jove (or Jupiter), after whom this planet is named.
Keep your Jupiter force close at hand to ward off depression, and to help you meet the world with confidence.
