Why this page won't tell you your future
Two people in the same Ketu-in-Mars period can live opposite stories, because what each planet delivers is set by the houses it rules and occupies in the individual chart — not by the combination alone. The honest way to read this period is to compute your chart, see what Mars and Ketu actually control for you, and verify the pattern against dated events from your own past before trusting forward-looking claims.
