Mercury is the planet of intelligence, communication, and mental abilities. The 9th house is the house of higher learning, travel, and spirituality. Aquarius is the sign of independence, rebelliousness, and humanitarianism.

When Mercury is retrograde, communication can become more challenging, and misunderstandings can arise. However, it can also provide an opportunity for introspection and deep reflection. Therefore, in the case of retrograde Mercury in the 9th house in Aquarius, you may have a deep curiosity for spiritual knowledge, philosophy, and religion.

However, you need to be careful while traveling during retrograde Mercury. Avoid important legal documents signing, and try to avoid any major communications and business deals during this period. You may need to be extra cautious while communicating with people, as there may be a higher likelihood of misunderstandings.
