The Pitru Mantra — "Om Pitru Devtaya Namah", the salutation to the Pitru Devatas (ancestors), chanted with Tarpan during Pitru Paksha and for Pitru Dosha shanti.
A salutation to the Pitru Devatas — the deified ancestors and the divine guardians of the ancestral realm. The accompanying verse "Devatabhyah Pitrubhyashcha" bows to the gods, the forefathers and the great yogis, and to Svaha and Svadha, the powers that carry offerings to the gods and to the ancestors.
Chanted while offering Pitru Tarpan with water and black sesame, during Pitru Paksha, on Amavasya and in Shraddh rites; recited for the peace and blessings of the ancestors and as a daily remedy for Pitru Dosha.
Om Pitru Devtaya Namah — "Salutations to the Pitru Devata," the deified ancestor; the simplest daily remembrance. Om Sarva Pitru Devtabhyo Namah — "Salutations to all the ancestral deities," embracing every forebear of the family line at once. The Pitru Smaran shloka ("Devatabhyah pitrubhyashcha...") bows to the gods, the ancestors and the great yogis, and to Svaha and Svadha — the two sacred utterances by which offerings reach the gods and the ancestors respectively. The Pitru Gayatri follows the Gayatri pattern: "We know the host of ancestors; we meditate on the upholder of the world; may the Pitrus inspire us."
Pitru mantras are chanted facing south — the direction of the ancestors — usually in the morning after bathing. During tarpan, water mixed with black sesame seeds is offered from the joined palms, released over the pitru-tirtha (the base of the right thumb), while the mantra is recited for each ancestor. Keep a calm, grateful frame of mind; tradition treats remembrance and gratitude, not elaborate ritual, as the heart of pitru worship.
The chief occasions are Amavasya (the new-moon day, sacred to the Pitrus each month), the fortnight of Pitru Paksha ending in Mahalaya Amavasya, and the annual Shraddh tithi of the departed — you can find the exact Shraddh day for a family member with the Shraddh Tithi calculator.
Traditionally the eldest son performs tarpan, but any descendant may remember the ancestors with these mantras — daily, on Amavasya, or through Pitru Paksha. In Vedic astrology, unresolved ancestral debt is described as Pitru Dosha in the birth chart, and daily recitation of the Pitru mantra is its gentlest classical remedy; you can check your chart with the Pitru Dosha checker.
The tradition places ancestor remembrance among the five daily debts (pancha-rina) every householder carries — to the gods, the sages, the ancestors, fellow humans and all creatures. The Pitru mantra discharges the ancestral debt in its simplest form: a moment of daily gratitude to those from whom body and life were received. Feeding a cow, a crow or a person in need on Amavasya, in the ancestors' name, completes the remembrance in the traditional way.
