The Amarnath Cave has great significance in Hinduism. Lord Shiva, according to legend, chose this cave to disclose to Parvati the secrets of immortality and the creation of the universe.
According to tradition, Parvati once begged Lord Shiva for the key to eternal life. He originally refused, but after her prodding, he agreed to reveal the secret.
To tell the story, Lord Shiva began looking for a lonely area where only Parvati could hear Amar Katha. He soon came across the Amarnath Cave. He left everything behind, including his bull Nandi in Pahalgam, his moon in Chandanwari, his snakes on the shores of Lake Sheshnag, his son Ganesha in Mahagunas Parvat, and his Five Elements at Panjtarni.
After that, Lord Shiva and Parvati entered the hallowed Amarnath Cave. He is said to have experienced samadhi while sitting on a deer skin. To guarantee that no living creature heard the secret Amar Katha, he created a rudra named Kalagni and instructed him to set fire to the land surrounding the cave, extinguishing all living beings. He then started telling Parvati the story of immortality. Despite these efforts, one egg remained hidden beneath the deer skin on which the Lord sat. According to folklore, that egg spawned a pair of immortal pigeons. The pigeon pair can still be seen when pilgrims approach the Amarnath Cave.
