You must have heard about the famous Amarnath Yatra in which many pilgrims participate every year to get the darshan of Shiv-lingam in ice form. This popular Yatra is organized by J&K government.
Amarnath cave only opens for a short span of time every year. Usually the Amarnath Yatra happens in the month of July and August (month of sharavan). Sometimes, due to uncertain climatic conditions, the date of Amarnath Yatra varies. It is believed that at the time of Amarnath Yatra, a Shiv-ling in ice form comes into being in the cave of Amarnath. This naturally made Ice-lingam comes in it full form on Purnima. It is said that on that day, Lord Shiva revealed the secrets of immorality and the creation of Universe to Mata Parvati. Amarnath is considered as the one of the most important Hindu Dhams. The holy cave of Amarnath is also considered as the residence of Lord Shiva.
It is believed that one day Goddess Parvati asked to Lord Shiva that why he wears the beads of heads. Lord Shiva replied to Maa Parvati that he adds one more bead whenever Maa Parvati is born. Goddess Parvati curiously asked to Lord Shiva that why she dies again and again and why Lord Shiva is immortal. She wanted to know the secrets behind the immorality of Lord Shiva. Lord Shiva tried a lot to postpone this question from Maa Parvati but after constant questioning, Lord Shiva decided to tell those secrets to Maa parvati. Before telling the secrets, Lord Shiva searched for a lonely place so that nobody else could listen them. He decided to go in Amarnath Cave. On the way, he left his Nandi (the bull of Lord Shiva) at Pahalgam. After that, moon was released from his Jatas (hairs) at Chandanwari. Snakes were released by him at the banks of Sheshnag lake. He also left his son Ganesha at Mahaganesh hills (Mahagunas Parvat). Lord Shiva did not want any living being at Amarnath cave so he decided to leave the five elements (Earth, Air, Sky, Water and Fire) which are responsible for making living beings. After leaving all these, Lord Shiva entered the holy cave of Amarnath with Maa parvati. Lord Shiva took Samadhi on deer skin and started concentrating. Lord Shiva did not want any living being there to hear the secrets of immorality. So, Lord Shiva created Kalagni and gave him orders to spread fire inside the cave and also at the surroundings of holy cave to eliminate all living beings present there. After ensuring, Lord Shiva started narrating the secrets to Mata Parvati. But somehow, an egg remained protected because it was lying under the skin of deer. It is believed that a pair of pigeons took birth from that egg and became immortal because they heard the secrets of immorality which also known as Amar Katha. Many devotees report about the seeing of a pair of pigeons on the way to Amarnath Yatra.
It is such a divine journey to the holy cave of Amarnath. It is not easy to reach at this holy shrine due to the uncertain climatic conditions. But with the blessings of Lord Shiva, many devotees every year participate in this divine Yatra. One must visit this holy shine to get the blessings of Lord Shiva. May Lord Shiva bless you!
