Pitru Dosha is created in many ways. The special combination of planets is responsible for creating this unfortunate Kundli Dosha. This dosha is created by Rahu in many ways. Pitra dosha can be understood on the basis of various positions or placement of Rahu in the horoscope.

Mangal dosha is formed due to the placement of Mars in the 1st, 4th, 7th, 8th or 12th house in a horoscope. However, in Southern parts of the country, the placement of Mars in the second house also gives birth to Mangal dosha. Thus, Mangal dosha completely depends upon the placement of natal Mars in any of these above mentioned houses.
