So how do these two energies interact with one another to create a meaningful and transformative journey? Are there pitstops and pitfalls along the way?

What Does the 12th House Indicate in Astrology?

The houses of astrology represent the steps we take throughout our lives, and the 12th house is the final stop. This house deals with endings, the subconscious, spiritual knowledge, and self-undoing.

The astrological chart is formed into a wheel, and because of this, we aren’t always climbing up, or walking on a linear path but moving in cycles.

The 12th house is the last stop on the astrological wheel, and it teaches us how to end well. It also reminds us that there are new beginnings on the horizon, and challenges us to let go of the past and move forward with new knowledge.

The 12th house is ruled by the planet Neptune and the astrology sign Pisces. These two archetypes represent the deeply imaginative, emotional, and mystical moments in life.

These energies urge us to work on personal transformation, confronting and negotiating our shadows, and creative manifestation.

What’s the Meaning of the Planet Mercury in Astrology?

Mercury rules the signs of Gemini and Virgo, two astrological archetypes known for their abilities to gather and sort information quickly.

While the Mercury in 12th house placement has many strengths, there are some challenges associated with this placement as well.

Since this individual tends to be a bit quiet and inward, it may be hard for them to establish or maintain close and genuine relationships.

While the Mercury in 12th house individuals enjoy the company of others, it can be a challenge for them to know how to connect. Their esoteric nature and spiritual power may feel off-putting to others at first.

As a result, this person may avoid sharing their personal struggles and start to manipulate others into thinking that they’re perfect.

  • Here are some additional challenges that Mercury in 12th house natives may encounter:

  • Overly secretive inclinations, leading to a sense of isolation
  • Easily manipulated by hidden enemies or false friends
  • Trouble speaking clearly and expressing the truth in social situations
  • Excessive escapism, living in an imaginative world to avoid aspects of reality

They may seek guidance in dream analysis, esoteric studies, and spiritual counsel. While this transit can be a time of emotional confusion and self-doubt, it’s also a great opportunity to explore the mysteries of life.
