Every year, on the second day of the bright fortnight of Ashadha (June–July), the three deities leave their temple. Three massive wooden chariots are constructed anew for each festival — Nandighosa for Jagannath (45 feet tall, 16 wheels), Taladhwaja for Balabhadra (44 feet, 14 wheels), and Darpadalana for Subhadra (43 feet, 12 wheels). Built from specified trees with wooden joints and cloth bindings and no iron nails, they follow ancient architectural prescriptions unchanged for centuries.
On the first day, the most iconic moment of the festival occurs: the Gajapati King of Puri, the temple's hereditary chairman, sweeps the chariots with a gold-handled broom. The gesture is a public declaration that before the Lord of the Universe, even a king is a humble servant. The chariots are then pulled by thousands of devotees along Bada Danda, the Grand Road, to the Gundicha Temple three kilometres away.
The festival lasts nine days. The deities reside in the Gundicha Temple — their garden house — and return on the ninth day in the Bahuda Yatra. The day after the return, they appear in their Suna Besha, adorned in gold jewellery weighing more than 100 kilograms. Over 60 festivals are observed at the temple each year, but none approaches the scale and emotional power of the Rath Yatra.
It was this spectacle that British travellers witnessed in the 19th century and described as an unstoppable force crushing everything in its path. The description entered the English language as 'juggernaut.' To this day, the Rath Yatra remains arguably the most visible public Hindu festival in the world, and its chariots are open to people of all faiths.
The Rath Yatra links Puri to the wider Char Dham pilgrimage circuit, of which the Jagannath Temple is the eastern cardinal point.
