Why do all Hindus consider Gaya the supreme Pitru Tirtha?

Gaya’s supreme status as Pitru Tirtha rests on a combination of scriptural authority and spiritual history: (1) Scriptural endorsement — the Vayu Purana dedicates entire chapters to Gaya Mahatmya, the Agni Purana prescribes Gaya as the first choice, and the Mahabharata records Yudhishthira’s Gaya pilgrimage, (2) Divine presence — Vishnu is physically present as Gadadhar, leaving the famous Vishnupad footprint, (3) Gayasura legend — the asura whose body became the sacred land of Gaya itself, consecrated by Vishnu, Brahma, and Shiva, (4) Sapta Pitri promise — scripturally guaranteed liberation of seven generations through a single ceremony, (5) Continuous tradition — millions of Hindu families have performed Pind Daan at Gaya for over 2,500 years, creating an unbroken chain of spiritual merit. No other tirtha in India carries this combination.
