retrograde Mercury rules 12th and 3rd house is in 4th house in Libra

As a Jyotish astrologer, the retrograde Mercury in the 4th house, which is in the Libra sign could indicate some challenges in communicating with family members and those close to the native. People with this placement may find it difficult to express their emotions, especially in a family setting. They may also face some issues related to their home or property.

However, the retrograde nature of the Mercury indicates that the native may have some unique and unconventional ideas related to their family life, which could prove to be beneficial in the long run. The retrograde placement also indicates that the native may have to work harder to communicate effectively in their personal life, but it also gives them the potential to become a better and more thoughtful communicator.

Overall, it is suggested for the native to take particular care in their communication and decision-making processes with family members, especially during Mercury retrograde periods, to prevent any miscommunication or misunderstandings.
