retrograde Mercury rules 8th and 11th house is in 9th house in Cancer

As a Jyotish astrologer, I would interpret retrograde Mercury in the 9th house of Cancer as a placement that may cause some challenges in matters related to higher education, spirituality, and long-distance travel.

Retrograde Mercury indicates that the native may struggle with clear communication and gaining knowledge or ideas. They may need to take extra time to fully understand concepts before being able to express them effectively. In the 9th house, this may especially manifest in difficulty grasping philosophical or spiritual concepts.

The Cancer sign of the 9th house emphasizes emotional and intuitive connections to both education and spirituality. This placement suggests that the native may feel a deep emotional connection to their studies or spiritual path, but may struggle to articulate those feelings or express them clearly to others.

However, retrograde Mercury can also bring a strong analytical and introspective side to the native's personality. They may be able to gain a deeper understanding of themselves through self-reflection and self-examination, and may be able to use this introspection to gain insight into philosophical or spiritual concepts.

Overall, this is a complex placement that may require some extra effort to fully realize its potential. The native may need to work harder than others to achieve success in higher education and spiritual pursuits, but with dedication and persistence, they may be able to excel in these areas.
