Mercury in the 6th sharpens problem-solving and analysis; good for accounting, law and medicine, though nervous stress needs managing.
What the 6th house governs
The 6th house, Ripu bhava, covers enemies, competition, illness, debts, service and daily work. It is an upachaya (growth) house, where results improve with time and effort.
What Mercury brings
Budh, Mercury, is the prince — intelligent, quick and communicative. It governs speech, trade, mathematics and learning.
What changes the result
- Sign and dignity: Mercury exalted or in its own sign gives the best version of this placement; debilitated or in an enemy sign, the weaker version.
- House lordship: which houses Mercury rules for your Lagna decides whose matters it carries into the 6th house.
- Aspects and conjunctions: Jupiter's aspect protects; Saturn, Mars or Rahu add pressure.
- Dasha: the placement shows most strongly during Mercury's own Mahadasha or Antardasha (17-year Mahadasha).
