Mercury rules 6th and 9th house is in 12th house in Sagittarius

Having Mercury placed in the 12th house of the Sagittarius sign indicates that your communication skills and analytical abilities are deeply connected with your spiritual and intuitive nature. This placement signifies a deep need to explore the inner realms of the mind and to gain knowledge about spirituality, philosophy, and meditation.

This placement also suggests that you may have a tendency to keep your thoughts and ideas to yourself or to isolate yourself from others. You might prefer to spend your time alone to think, read, and write.

Since Sagittarius is a sign of exploration and expansion, this placement can also indicate a strong interest in foreign cultures, travel, or higher education. You might excel in fields such as philosophy, teaching, spirituality, or writing.

However, the placement of Mercury in the 12th house can also indicate that you may face some obstacles with communication, especially when it comes to expressing your feelings or confronting emotional situations. You might also struggle with insomnia or have an overactive mind, which can make it difficult to relax or find peace.

Overall, this placement suggests a deep connection between your intellect and your spirituality, and you might find fulfillment through exploring your inner world and sharing your insights with others.
