Amriteshwar Temple, one of many Shiv Lings established in Varanasi, Uttar Pradesh. Based on a story, mentioned in Kashi Khand, the Amriteshwar Shiv Ling was established by a boy named Shanaru.
In the past, Shanaru lived in Kashi as a Grihastha Rishi—a Rishi who follows a typical family life. He used to adhere to all the Sanatana Dharma-established rules for prayer. He constantly carried out Linga Pooja, Brahma Yagnam, and all other connected rites.
One day, as the youngster was playing in the adjacent jungle, his son Upajangini was bitten by a snake and his body turned lifeless. The Sage carried the body to a location near Swarg Dwar in Kashi, which was close to Mahasmashan, after learning of his son’s passing (cremation ground). He buried the youngster in a pile of muck and then began to consider how to proceed with the cremation.
Unknown to him, there was a little Ling beneath the surface that resembled a gooseberry in both size and form (amla). Because of the Shiv Ling’s radiation, the youngster Upajangini, who had been proclaimed dead, awoke as though from a profound sleep. The sage was astonished by what had occurred. One snake, carrying a dead worm in its jaws, traveled across the muddy region precisely at that moment.
The dead worm sprang back to life as soon as it touched the muddy region. The sage pondered whether there is something that must hold Amrita Sanjivini in that muddy place (An elixir capable of overcoming death).
He began poking about in the muck and discovered one little Ling that was about the size and shape of a gooseberry. The sage removed the Shiv Ling from the mud right away, followed all the rites, and then erected it ceremonially. After that, he began to worship the Shiv Ling whom he later gave the name Amriteshwar. Kashi Khand’s Chapter 94 states that those who touch Amriteshwar Ling would achieve Amritatva (victory over death).
According to certain accounts, the Shiv Ling has the capacity to bring the dead back to life. It is also claimed that individuals who offer prayers to Amriteshwar won’t worry about reincarnation. In addition, Lord Shiva informs Goddess Parvati in Kashi Khand, Chapter 73, about fourteen potent Shiv Lings in Kashi that can grant followers Mukti. The first of Lord Shiva’s fourteen mentioned deities is Amriteshwar.
