Frequently asked questions

What is Pitra (Pitru) dosha?
A chart pattern read as unresolved ancestral karma — classically flagged when the Sun (father/ancestor karaka) is afflicted by Rahu or Ketu, or when the nodes afflict the 9th house of forefathers. It is associated with recurring family obstacles and is addressed through shraddha rites.
Is Pitra dosha the same as a curse?
No — the tradition frames it as a debt or duty owed to ancestors, not a malediction. The indicated response is remembrance and ritual care (tarpana, shraddha, pind-daan), which is why the remedies are devotional rather than defensive.
Which days address Pitra dosha?
Pitru Paksha — the waning fortnight of Bhadrapada/Ashwin (September–October) — is the principal window for shraddha and tarpana, especially Sarva Pitru Amavasya. Monthly Amavasya days, and Gaya/ Prayag/ Haridwar pind-daan, are the established venues for the fuller rites.
Can this calculator confirm the dosha by itself?
It verifies the standard astronomical triggers precisely — conjunctions and house placements are computed, not guessed. But weighing severity needs the whole chart (9th lord, Jupiter’s aspects, dasha context), so treat a “yes” here as grounds for a proper reading, not a sentence.
What are the common remedies?
Regular shraddha/tarpana for departed elders, Pitru Paksha observance, feeding brahmins/the needy on Amavasya, Surya arghya (water offering to the Sun) and Maha Mrityunjaya or Gayatri japa. Lineages add Trimbakeshwar/Gaya rites for strong cases.
