How Mercury can change your personality type

If I were to summarize why I love personality typology and astrology, it is because they can help us see and become who we already are.

In the Jungian world, personality typology is a stepping stone to wholeness and to discovering who we already are. Jung described the end result as the “transcendent function.”

Here is one of my favorite definitions of the transcendent function, from Jungian analyst Polly Young Eisendrath:

Resisting our tendencies to defend our complexes, we develop an ability that Jung called the “transcendent function.” It is the capacity to hold tensions and let a meaning emerge without prematurely deciding whether a situation is “good” or “bad.”

The Resilient Spirit by Polly Young Eisendrath, p. 150

From a personality type perspective, Marie Louise-von Franz, Jung’s close associate, described it as how the first step is to assimilate our dominant function. Then we make the second more conscious and, eventually, the third. The inferior function always remains a problem and we can’t approach this function directly. Jung said the practice of active imagination is the best way to approach it. Painting, dancing, and other creative expression can help.

Additionally, focusing on the middle two functions of the personality type through active imagination forms a “middle ground” of the personality – a kind of “inner center” – and you can start using the functions at will instead of unconsciously. Remember that in the first half of life the focus is on developing the middle two functions of our personality type, with one of those becoming the auxiliary function. In the last half of life the focus turns to the inferior function.

Knowing where Mercury is in your astrology natal chart can help with this process. In the book Inner Planets, Howard Sasportas says Mercury is the mostly closely related to the transcendent function:

The secret of alchemy was in fact the transcendent function, the transformation of the personality through the blending and fusion of the noble with the base components, of the differentiated with the inferior functions, of the conscious with the unconscious. I believe that Mercury is the planet most closely aligned to the transcendent function.

Mercury was the only god that could go to the underworld and return. This back-and-forth quality of Mercury helps us unite the opposites within us. Mercury is also associated with communication, mediation, business, negotiation, analysis, and even back-and-forth games like tennis, pickleball (my favorite), basketball, and so on. Mercury also shows where we need variety and change and how we like to be playful and curious.

The zodiac wheel is divided into 12 areas of life called houses. Take a look at your natal chart to see which house and zodiac sign Mercury is in. This will show how Mercury can help bring the opposites together within you, in regards to personality type, and also the opposites form without in relationships and interactions with others.

For example, if Mercury is in Pisces in your 7th house of relationships this points to a more creative form of Mercury. Giving space to creative expression in whatever form appeals to you will make your personality flourish. Active imagination will probably come easy to you. Spirituality may also be important to you. Mercury here also means that relationships will play a key role in discovering who you already are.
