retrograde Mercury rules 3rd and 6th house is in 4th house in Cancer
As a Jyotish astrologer, retrograde Mercury in the 4th house of Cancer sign indicates that the native may have communication issues within their family or personal life. This person may have a unique way of expressing themselves but it may not always be received positively by their family members. They may also have trouble trusting their own intuition and may rely heavily on the opinions of others.
This placement also suggests that the native may have a keen interest in learning about psychology, history or any other subject that relates to emotions and the human mind. Retrograde Mercury may make it a bit difficult for the native to express their views effectively, but with dedication and practice, they can improve their communication skills.
This placement also indicates that the native may be prone to over-thinking or worrying about their home life. They may be overly attached to their home and may find it hard to leave it on a long-term basis. The native may also experience delays or challenges while buying or selling their house or property.
The positive aspect of this placement is that the native may possess excellent analytical abilities and may be very perceptive when it comes to emotions and feelings. With time and effort, the native can learn to use these abilities to their advantage and create a well-balanced, peaceful home life.
