Discovery of Holy Cave
According to legend, Bhrigu Muni was the first to have discovered Amarnath. Long time ago it is believed that The Valley of Kashmir was submerged under water and Kashyap Muni drained it through a series of rivers and rivulets. Therefore, when the waters drained, Bhrigu Muni was the first to have Darshan of Lord Amarnath. Thereafter, when people heard of the Lingam, it became an abode of Lord Bholenath for all believers and a pilgrimage which is done by lakhs of people each year. According to the researchers and as per the belief of locals gadaria community were the first to discover the Amaranth cave and saw the first glimpse of Baba Barfani.
Francois Bernier, a French physician accompanied Emperor Aurangzeb during his visit to Kashmir in 1663. In his book "Travels in Mughal Empire" he writes while giving an account the places he visited in Kashmir that he was "pursuing journey to a grotto full of wonderful congelations, two days journey from Sangsafed" when he "received intelligence that my Nawab felt very impatient and uneasy on account of my long absence". The "grotto" he refers to is obviously the Amarnath cave as the editor of the second edition of the English translation of the book, Vincient A. Smith makes clear in his introduction. He writes: "The grotto full of wonderful congelations is the Amarnath cave, where blocks of ice, stalagmites formed by dripping water from the roof are worshipped by many Hindus who resort here as images of Shiva.
