Chandra grahan dosha (also written Chandra graha dosha) forms when the Moon sits in the same sign as Rahu or Ketu in the birth chart — a symbolic eclipse of the Moon. It is strongest when they are within a few degrees and the Moon is weak. It is read mainly for the mind: worry, mood swings and restlessness, especially in Moon, Rahu or Ketu periods. It is not about the Moon in the 2nd, 4th, 7th or 12th house.

How it forms
- Moon + Rahu in one sign: restlessness, overthinking, unusual fears or ambitions.
- Moon + Ketu in one sign: detachment, low mood, a pull toward spirituality.
- Birth during a lunar eclipse is taken as the strongest form.
How strong is it?
- Close degrees count far more than a loose conjunction in the same sign.
- A dark Moon (near Amavasya) or the Moon in Scorpio makes it heavier; a bright Moon in Taurus or Cancer softens it.
- Jupiter’s aspect on the Moon is a strong protection.
- The house shows the area of life it touches — for example the 4th for home and peace of mind.
When it shows
Mostly in the Moon, Rahu or Ketu mahadasha or antardasha, and when transiting Rahu or Ketu crosses the natal Moon. Many people with a mild form notice little outside these periods.
Remedies
- Shiva worship on Mondays; water or milk on the Shivling.
- Chandra mantra Om Shraam Shreem Shraum Sah Chandraya Namah on Mondays; Rahu or Ketu mantra on Saturdays or Tuesdays, 108 times.
- Charity of rice, milk or white cloth, and prayer during eclipses.
- Steady sleep and routine; for persistent anxiety or low mood, see a doctor — remedies are support, not treatment.
