Amarnath cave is a Hindu shrine located in Jammu and Kashmir, India. The cave is situated at an altitude of 3,888 m (12,756 ft), about 141 km (88 mi) from Srinagar, the summer capital of Jammu and Kashmir and reached through Pahalgam town. The shrine forms an important part of Hinduism, and is considered to be one of the holiest shrines in Hinduism. The cave is surrounded by snowy mountains. The cave itself is covered with snow most of the year except for a short period of time in summer when it is open for pilgrims. Hundreds of thousands of Hindu devotees make an annual pilgrimage to the Amarnath cave on challenging mountainous terrain to see the almighty linga, which is an ice stalagmite formed inside the cave.
Inside the 40 m (130 ft) high Amarnath cave, the stalagmite is formed due to freezing of water drops that fall from the roof of the cave on to the floor and grows up vertically from the cave floor. It is considered to be a Shiva Linga by Hindus. It is mentioned in the ancient Hindu texts of Mahabharata and Puranas that Lingam represents Lord Shiva. The Cave waxes during May to August, as snow melts in the Himalayas above the cave and the resultant water seeps into the rocks that form the cave and gradually wanes thereafter. As per religious beliefs, it has been claimed that the lingam grows and shrinks with the phases of the moon reaching its height during the summer festival, although there is no scientific evidence for this belief.
According to a Hindu legend, this is the cave where Shiva explained the secret of life and eternity to his divine consort, Parvati.The book Rajatarangini (Book VII v.183) refers to Amareshwara or Amarnath. It is believed that Queen Suryamathi in the 11th century AD gifted trishuls, banalingas and other sacred emblems to this temple. Rajavalipataka, begun by Prjayabhatta has detailed references to the pilgrimage to Amarnath Cave. Other than this, there are further references to this pilgrimage in many other ancient texts.
According to legend, Bhrigu Muni was the first to have discovered Amarnath. Long time ago it is believed that The Vale of Kashmir was submerged under water and Kashyapa 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.
