Ketu (केतु) in Vedic astrology — what it governs, how to read it, when it activates
Ketu is one of the nine grahas of Vedic astrology. It governs moksha, detachment, spirituality, past-life karma. This guide covers Ketu's essential nature, how to read its strength in your chart, what its dasha period brings, and the standard remedies when it's afflicted.
Ketu's essential nature
Ketu is a karaka (significator) of moksha, detachment, spirituality, past-life karma. In any chart, Ketu's strength tells you the baseline quality of these life areas. Ketu is considered strong when it occupies its own sign or its sign of exaltation, when it aspects beneficially, and when it's not combust, retrograde with affliction, or in 6/8/12 houses (with caveats — Saturn in 6 is actually a yoga).
How to read Ketu in your chart
Look at four things: (1) Ketu's house — the area of life it directly affects; (2) Ketu's sign — the mode in which it operates; (3) Ketu's aspects — what it strengthens or weakens elsewhere; (4) Ketu's nakshatra — the deepest layer of its expression. A simple cross-check: is Ketu where YOU feel strong about moksha, detachment, spirituality, past-life karma? If yes, the chart confirms the lived experience. If no, look for affliction.
Ketu's mahadasha — what to expect
When Ketu's mahadasha (or significant antardasha) activates, the themes of moksha, detachment, spirituality, past-life karma come to the foreground. This is when promised yogas deliver and afflicted placements show their weight. The classical Vimshottari dasha sequence runs: Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17, Ketu 7, Venus 20 years. Identify which Ketu-period you're in (or approaching) and read the chart through that lens — generic forecasts that don't account for dasha are nearly useless.
Remedies when Ketu is afflicted
Universal-safe remedies for Ketu: chant its bija mantra, donate items associated with Ketu on its day of the week, fast on its day, visit a temple of its presiding deity. Gemstone remedies (e.g. Ruby for Sun, Pearl for Moon, Red Coral for Mars, Emerald for Mercury, Yellow Sapphire for Jupiter, Diamond for Venus, Blue Sapphire for Saturn) require expert consultation — wrong stones backfire. The deeper Vedic view: planets are reflections of our karma. The remedy works when the karmic pattern itself shifts.
