Mercury rules 3rd and 6th house is in 1st house in Aries

As a Jyotish astrologer, I would interpret the placement of Mercury in the 1st house in Aries as follows:

• Mercury represents communication, intelligence, and analytical ability. It also governs siblings, communication skills, and business dealings.
• The 1st house represents the self, the physical body, and how one is perceived by others.
• Aries is a fire sign, which is energetic, impulsive, and action-oriented.

When we combine these factors, we find that individuals with Mercury in the 1st house in Aries are likely to be quick-minded, intellectual, and sharp-witted. They are likely to have strong communication skills and may excel in areas such as writing, teaching, or public speaking. They may also have a good sense of humor and enjoy lively debates.

However, since Aries is a sign associated with impulsivity and lack of foresight, individuals with this placement may need to be careful not to jump to conclusions or act hastily without thinking things through. They may also have a tendency to be argumentative or confrontational, which could lead to conflict in personal or professional relationships. Additionally, this placement may make them prone to headaches or other ailments related to the head and nervous system.

Overall, this placement gives individuals a strong mental acuity and the ability to think on their feet, but it is important that they learn to balance their quick wit with a sense of caution and consideration for others.
