NESTA, village 2 km south of Atari in Amritsar district of the Punjab, is sacred to Guru Hargobind (1595-1644) who stayed here for a while during his journey from Lahore to Amritsar. According to local tradition, at the villagers` complaint that the water of their well was brackish, the Guru had them dig another well close to it. The water of this well was sweet (mittha, in Punjabi). Both these wells still exist side by side. The shrine established here came to be called Mitthasar.

Gurdwara Mitthasar Chhevinri Patshahi, as it is now named, is situated north of the village close to the approach road from Atari. Its present building, constructed in 1930 in a half acre walled compound, comprises a modestsized hall with a domed sanctum inside it. The Gurdwara is managed by a village Committee under the auspices of the Shiromani Gurdwara Parbandhak committee.
