In Vedic astrology, Rahu and Ketu are shadow planets known as Chaya Grahas, representing karmic influences from past lives. When these planets occupy critical positions in a birth chart (Jathagam), they can create Rahu–Ketu Dosha, a condition that affects emotional balance, relationships, and marital harmony. Understanding their placement is essential during Kundali or Jathagam matching to ensure a stable and peaceful married life.Rahu and Ketu are lunar nodes that do not possess physical bodies but represent eclipsing energies—Rahu symbolizes obsession, illusion, and worldly attachment, while Ketu represents detachment, spirituality, and liberation. When these planets occupy critical positions—especially in the 1st, 5th, 7th, or 8th houses—they can create Rahu–Ketu Dosha, which may influence a person’s relationships and marital harmony.
