The Seventh Chakra is our connection to our Higher Self, the place through which divine wisdom enters. But why Mercury for this chakra? Shouldn’t the planet be something, I don’t know, loftier? Well, there are a couple of reasons for this choice.
First off, in mythology Mercury is the messenger of the gods; you know, the guy with wings on his heels, like in the FTD logo. It seems natural to assign the planet Mercury to this chakra, then. Also, Mercury is the communications planet in astrology. Where our Mercury is in our natal chart shows how we think and communicate.
Astronomically, Mercury is the closest planet to the Sun, and the Sun is seen in many esoteric traditions as the physical manifestation of the divine in our solar system. As such, Mercury is the intercessor, in that it lies between us and that representation of the godhead. Notice in The Magician, the figure stands with one arm aloft and the other down, directing the force from the above to the below – once again, an intercessor, a messenger, and a transducer of the power from the divine.
But the associations don’t end there. The metal for Mercury is, as you may have guessed, mercury or quicksilver. This curious element is a liquid at room temperature and runs about quickly (if you’ve ever played with it, you know it forms globules and balls that shimmer and move away at a touch). Furthermore, mercury is seen in alchemy as the symbol of the superconscious, the highest source of communication. Sulfur is symbolic of our regular consciousness, while salt is the unconscious, or automatic consciousness.
Too much Mercury leads to a disorganized mind, flitting from one topic to the next, a very ungrounded situation. Too little Mercury beings a dullness of thought, and a rigidity of belief untempered by a true connection to the divine.
The note for Mercury and the Seventh Chakra is E natural. This is the beginning note of the Phrygian mode, a mode used to evoke rapid movement and quickness. It is often used in flamenco music, for example.
Mercury – communication and communion. Listen carefully and you will be able to hear the whisperings of the divine.
