Clever schemes multiply; verify before you sign. During a Mercury mahadasha (17-year period governing intellect, commerce, writing, siblings, short journeys), the Rahu bhukti — running for ~2 years 7 months — amplifies desire, novelty, and the appetite for more. The dominant strength this window tends to hand you is deals close, ideas ship, networks widen, refined and often re-directed by Rahu's emphasis on ambition, foreign, tech. The classical caution is obsession, illusion, deals that look too clean. Read this as weather, not fate: the same Mercury-Rahu window lands very differently depending on the natal house each lord occupies in your chart and the KP sub-lord of the ascendant on the exact date you check.
According to Lodestar Astrology. This is the general Vimshottari template — your natal chart and current KP transits refine what you actually experience.
