"Kundli Dosha," also known as "Kundali Dosha" or "Janam Kundli Dosha," refers to various astrological conditions or combinations in a person's birth chart (kundli) that are believed to have negative effects on different aspects of their life.

These doshas are based on the positions of planets, lunar nodes (Rahu and Ketu), and other astrological factors at the time of a person's birth. Some of the common doshas found in Kundli are:

1. Mangal Dosha: As mentioned earlier, this dosha occurs when the planet Mars (Mangal) is positioned in certain houses of the birth chart. It is believed to affect marriage and relationships.

2. Kaal Sarp Dosha: This dosha occurs when all the planets are placed between Rahu (the North Lunar Node) and Ketu (the South Lunar Node) in the birth chart. It is believed to bring challenges and obstacles related to various aspects of life.

3. Grahan Dosha: Grahan Dosha occurs when a person is born during a solar or lunar eclipse. It is considered inauspicious and may bring difficulties in life.

4. Pitra Dosha: Pitra Dosha occurs when the ancestors of a person have not been properly honored or respected. It is believed to create obstacles and problems in life, especially related to family and progeny.

5. Shani Dosha: Shani Dosha, also known as Saturn Dosha, occurs when the planet Saturn (Shani) is placed unfavorably in the birth chart. It is believed to cause delays, hardships, and challenges in various aspects of life.

6. Nadi Dosha: Nadi Dosha occurs when the Nadi (pulse) of the prospective partners in marriage is the same. It is believed to cause health issues and conflicts in married life.

There are various remedies and rituals prescribed in Vedic astrology to mitigate the effects of Kundli Dosha, including prayers, charitable acts, gemstone recommendations, and performing specific rituals or poojas. However, it's important to note that interpretations of Kundli Dosha and the remedies may vary among astrologers and different schools of astrology.
