Gaumukh Temple,Mount Abu
The Gaumukh Temple as name suggest is made in the form of mouth of an cow.The Sage Vashishtha lived here with his wife and the wish fulfilling cow, gifted to him by the Devas, after they obtained it from the churning of the ocean, with eight other jewels! He is credited to have brought Nandi Vardhan Mountain, the youngest son of Himalayas, to Mount Abu. The incredible flying snake, Arbud Naag, who brought the gargantuan mountain from the South on its back, demanded the mountain to be named after him as "Arbudanchal" for the recognition of his services in bringing the great mountain from the South to its present address.
There is also a tank that you should visit- the Agni Kund. The Agni Kund is believed to be the site of a sacrificial fire which Saint Vashishth used to perform the yagni from which the four clans were born.The cow is considered a sacred animal by those who make religious pilgrimages to the Gaumukh Temple and nearby the temple you will find a spring that is believed to have emerged from the mouth of a rock that is shaped similar to a cows head. A large marble statue of a cow has been built on the site. The bull is representative of Nandi, who was Shiva’s vehicle. There is a stream of water that flows from the mouth of the marble bull. Nearby you will find statues of Nandi, Saint Vashishth, Lord Ram and Lord Krishna.
It is authentically mentioned in Van Perva of Mahabharata, where Sage Ved Vyas sways Dharma Raj Udhishtar to spend one night at Vashishtha Ashram, and further enlightens that a night's stay at the Ashram would bless him with the blessing, equivalent to giving one thousand cows in charity.
