When Mercury is in the 8th house, it can bring deep intelligence and curiosity, but it may also create challenges like overthinking, financial instability, or hidden disputes. To balance these energies and enhance the positive influence of Mercury, Vedic astrology recommends certain remedies:
1. Chant Mercury (Budh) Mantras
Reciting mantras is one of the most powerful ways to strengthen Mercury’s energy. Chant the Budh Beej Mantra – “Om Bum Budhaya Namah” daily, preferably 108 times on a Wednesday. This helps calm the restless mind, improve focus, and bring clarity in relationships and finances.
Mercury is associated with the color green. Natives with Mercury in the 8th house can donate green clothes, green vegetables, or green bangles on Wednesdays to attract positive Mercury energy. This also reduces conflicts and brings stability in joint financial matters.
3. Handle Shared Finances with Discipline
Since the 8th house governs inheritance, shared wealth, and partnerships, people with Mercury in 8th house must adopt discipline in financial dealings. Keeping transparent accounts and avoiding secretive money matters ensures stability.
4. Wear Emerald Gemstone (Panna)
Wearing a high-quality Emerald gemstone can enhance Mercury’s beneficial impact. However, this remedy should only be done after consulting a qualified astrologer, as wearing gemstones without proper guidance can backfire if Mercury is afflicted.
5. Meditate and Practice Mindfulness
Mercury in the 8th house may cause anxiety or over-analysis. Daily meditation, pranayama, and mindfulness exercises calm the mind and reduce restlessness. These practices also strengthen intuition, helping natives make better decisions in relationships and finances.
6. Strengthen Communication with Family & Partner
Since the 8th house also affects relationships and secrecy, practicing open and transparent communication can reduce misunderstandings. This balances Mercury’s tendency to hide or overthink.
