‘Grahan’ means eclipse. Grahana Dosha means the shadow planets (Chaya Grahas) Rahu or Ketu are in close conjunction with the Sun or Moon at the time of your birth, or if you are born during the eclipse. The Sun or Moon will come in the same house as Rahu or Ketu in a native’s birth chart or during the Lagna period. This means a newborn will have Grahana Dosha in the birth chart.
