There is an sanskrit shloka that lists the twelve jyotirlinga temples.
“Saurashtre Somanathamcha Srisaile Mallikarjunam|
Ujjayinya Mahakalam Omkaramamaleswaram ||
Paralyam Vaidyanathancha Dakinyam Bheema Shankaram |
Setu Bandhethu Ramesam, Nagesam Darukavane||
Varanasyantu Vishwesam Tryambakam Gautameethate|
Himalayetu Kedaaram, Ghrishnesamcha shivaalaye||
Etani jyotirlingani, Saayam Praatah Patennarah|
Sapta Janma Kritam pApam, Smaranena Vinashyati||”
Mahadev, the Lord incorporates in Himself, the aura and the holiness of all the twelve JyotirLingas. The grandeur of these places is unique. Devotees line up in great numbers to take a look and get a Darshan of all the JyotirLingas.
Location of the Jothirlinga temples
Two on the sea shore, three on river banks, four in the heights of the mountains and three in villages located in meadows; the twelve Jyotirlingas are spread out like this. Every place has been described in glorious words by many detailing the surroundings etc.
Those of us who go to these temples of Shubhankar Shankar- Jyoti-Sivasthan, receive the holy blessings of the Lord, and come back happy, peaceful and blessed. This in indeed depends on one’s devotion and experience too.
