Pitra dosh — ancestral affliction — shows in the chart through Sun/Moon afflictions involving Rahu-Ketu or the 9th house, and shows in life through a signature pattern: recurring obstacles across generations, family discord without cause, and progress that dissolves near completion.
Remedies are among astrology’s gentlest: shraddha and tarpan for ancestors, pipal seva, feeding the needy on amavasya. Where the dosh is confirmed and deep, a formal Pitra Shanti puja is prescribed. Verify before remedying — get the chart checked.
