The question asks to identify the specific pilgrimage site in Haryana where the unique "Surya Grahan Mela" (Solar Eclipse Fair) is organized during a solar eclipse. Haryana is known for its numerous historical and religious sites.
Kurukshetra is a significant city in Haryana, revered as a major pilgrimage destination, especially for Hindus. The city holds immense religious importance, being associated with the Mahabharata epic and the Bhagavad Gita.
Among the various sacred sites in Kurukshetra, Brahma Sarovar is particularly notable. It is a large ancient water body, considered holy, where devotees often take ritualistic baths, especially during auspicious occasions like solar eclipses.
It is a well-known tradition that during the event of a solar eclipse (Surya Grahan), a special fair, the "Surya Grahan Mela," is held at Brahma Sarovar in Kurukshetra. This fair attracts a large number of pilgrims and tourists who gather to witness the eclipse and participate in religious activities and rituals performed at the sarovar.
The other options, Bhishma Kund, Sheikh Chilli's Tomb, and Jyotisar, are also significant sites in Kurukshetra, but the specific Surya Grahan Mela is primarily associated with Brahma Sarovar due to its large bathing ghats and prominence during eclipse events.
