The Mercury dasha period

In the Vimshottari system the Mercury mahadasha runs for 17 years. During it, matters of intellect, speech, trade, learning move to the centre of life. What the period actually delivers depends on which house and sign Mercury occupies — supportive when exalted in Virgo, harder when debilitated in Pisces.

Signs of a strong Mercury

When Mercury is strong, matters connected with intellect, speech, trade, learning move smoothly, confidence in those areas holds up, and decisions about them get made on time.

Signs of a weak Mercury

A weak or afflicted Mercury shows up as repeated delay, confusion or dissatisfaction in matters of intellect, speech, trade, learning. This is indicative only — house placement and dasha must be read together.
