Rahu Mahadasha — Budh (Mercury) Antardasha
Inside the 18-year Rahu mahadasha, the Budh (Mercury) antardasha runs for 2 years 6 months 18 days as sub-period 4 of 9. Lightens the mind — study, business, communication and travel move quickly. The two lords are natural friends, so the sub-period tends to flow WITH the mahadasha theme — efforts compound rather than collide.
Classical basis: the Vimshottari sub-period rule of Brihat Parashara Hora Shastra — the antardasha spans (mahadasha years × antardasha lord’s years) ÷ 120, sub-periods run in the fixed order from the mahadasha lord, and the fruit is judged by the two lords’ mutual relation and the antardasha lord’s dignity in the birth chart.
