Pilgrimage
Puri
The eastern dham. Jagannath, the chariot festival, and mahaprasad.
When
All year. The Rath Yatra in Ashadha is the great gathering.
Region
Odisha
In Puri, Jagannath, Balabhadra, and Subhadra share one platform. At Rath Yatra the murtis go to the Gundicha house and return. Mahaprasad is its own custom — do not treat it as a restaurant plate. The temple has its own dress and conduct. Learn them first.
The sea is near, and it has its own warnings. Do not confuse the tirth with the surf. On chariot day, kindness is a high and quiet place from which elders can see.
This is a general introduction. Sequence, materials, and timing change with family, region, and shakha. Your priest and your own custom have the last word.
