retrograde Mercury rules 9th and 12th house is in 3rd house in Sagittarius

As a Jyotish astrologer, I can explain the effects of retrograde Mercury in the 3rd house of a Sagittarius sign as follows.

Firstly, the third house represents communication, siblings, short travels, and nearby surroundings. Retrograde Mercury in this house shows that the individual may face challenges in communication with people around them, especially siblings, and coworkers. There could also be a tendency to get involved in arguments and debates, which may lead to misunderstandings.

Secondly, as Sagittarius represents higher knowledge, philosophy, and spirituality, this placement may create an urge in the individual to delve deeper into these subjects. However, due to the retrograde Mercury, they may find it challenging to convey their thoughts or ideas to others effectively.

Thirdly, this placement may cause some hurdles in short-distance journeys or travel plans, which may get delayed or cancelled. The individual may need to be extra diligent in planning their schedules, to avoid these obstacles.

Overall, retrograde Mercury in the 3rd house of Sagittarius sign may cause some communication and travel-related challenges; however, it also offers opportunities to gain spiritual insights and knowledge. The person may need to work on their communication skills and avoid unnecessary arguments or debates, to sail through this period smoothly.
