Ketuकेतु

Ketu is the south node of the Moon — the point where the Moon's orbit crosses the ecliptic moving southward. It is always exactly opposite Rahu. Like Rahu, it has no physical body but is treated as a planet in Vedic astrology, with its own dasha period and interpretive qualities.

Associated with: spiritual orientation and detachment from material concerns, moksha (liberation), deeply embedded past patterns (whether understood in karmic terms or simply as ingrained conditioning), mysticism and occult knowledge, sudden separations, and things that feel familiar but whose source is obscure. Also associated with maternal grandfather in classical signification tables.

Where Rahu amplifies worldly desire and reach, Ketu tends to withdraw. Its placement often shows where a person feels little drive to accumulate or assert — sometimes because that domain feels already known, already exhausted, or simply unimportant.

Ketu is excluded from Jaimini's eight-karaka scheme. SahiKundli follows this convention: only Rahu is included among the eight karakas, counted in reverse (30° minus its longitude within the sign). Ketu is not assigned a karaka rank.

Used on SahiKundli for: Ketu's placement in houses and signs, Kaal Sarp yoga analysis, and Vimshottari dasha periods.
