సూర్య కుండం, యమునోత్రి

Surya Kund has been a pilgrim site for centuries; references to the Yamunotri shrine and its hot spring appear in medieval Garhwali tradition and in the accounts of pilgrims through the Char Dham route. The shrine itself was formally re-consecrated in the 19th century by Maharaja Pratap Shah of Tehri Garhwal, who built the present small temple of Yamuna Devi. The kund's stone-paved structure, with its containment wall and the cord-anchor for lowering rice-bundles, dates from the 19th-20th centuries; earlier the kund was an unwalled natural spring. The site has been damaged and rebuilt several times after floods and avalanches — most recently after the 2013 Uttarakhand cloudburst, which devastated much of the Yamunotri trail. The present stone-paved kund is a careful reconstruction faithful to the older pattern.

Surya Kund is a small stone-paved tank, roughly two metres across, walled on three sides with the natural spring rising at its centre. The water is held within carved stone — gray Himalayan granite — with a containment wall keeping the boiling spring contained for the cooking-ritual. A simple wooden cord-anchor at one edge allows pilgrims to lower their muslin cloth bundles (potlis) of rice and potatoes into the water and retrieve them safely. Just above the kund stands the small Yamuna Devi temple, a modest stone-and-wood Garhwali shrine with a low shikhara, weather-worn by the high-altitude climate. Adjacent to Surya Kund is Gauri Kund, slightly cooler, used for the ritual bath that the hotter Surya Kund cannot support. The whole tirtha-complex — Surya Kund, Gauri Kund, Yamuna Devi temple — is held within a small stone-walled compound on the steep slope below Kalinda Parvat.

The principal ritual at Surya Kund is the cooking of the prasad. Pilgrims arrive at the kund with raw rice and small unpeeled potatoes — available at stalls along the Janki Chatti trek and at Yamunotri itself, often pre-bundled in a small muslin cloth (potli). The potli is tied to a long cord, lowered into the boiling kund water, left for a few minutes, and drawn out fully cooked. The pilgrim then carries the warm bundle a few steps up to the Yamuna Devi temple, offers it to the goddess as bhog, receives it back as prasad, and shares it with family.

Surya Kund itself is not for bathing — the water is far too hot. The adjacent Gauri Kund, fed by the same hot spring but tempered by mixing, is the bathing-kund. Pilgrims typically bathe in Gauri Kund first, then cook the prasad at Surya Kund, then take Yamuna-darshan at the temple — completing the three-fold ritual in that traditional sequence.
