Ripu Bhava — enemies, debts, disease, service, daily work
Mercury in the house of service, debt and illness works better than its dusthana status suggests. It suits accountancy, medicine, law, systems administration — anything where the detail is the job and the adversary is disorder. Litigation is handled well because the paperwork is handled well. Nervous strain is the honest cost.
The 6th house is the obstacles you overcome by labour, governing enemies, debts, disease, service, daily work. Mercury (Budha) is a neutral that takes the colour of its company and signifies intellect, speech, commerce, learning, skill; its drive is to understand, to communicate, and to trade.
The 6th is a dusthana (difficult house), where planets deliver results through struggle, delay, or transformation. A benefic such as Mercury here may find its natural significations tested — the house consumes some of what the planet would otherwise give freely.
Three things modify this placement more than anything else: the sign Mercury occupies (see Mercury through the signs), the aspects it receives — Jupiter's aspect can rescue a difficult placement and Saturn's can sober an easy one — and the strength of the 6th house lord. Read this as one factor, not a verdict.
