Jyotirlingas are devotional representations of the Hindu god Shiva. The word "Jyotirlinga" is a Sanskrit compound of "jyotis" meaning light and "linga" meaning sign or image. Originally, there were believed to have been 64 Jyotirlingas, but twelve are considered to be very auspicious and holy. Each of the twelve Jyotirlingas is considered a different manifestation of Shiva and takes the name of its respective presiding deity. The primary image at these sites is a lingam, representing the infinite nature of Shiva. The 12 Jyotirlingas are located in different parts of India, and each has a unique story behind its formation. They are considered sacred sites for Hindus, and visiting all 12 Jyotirlingas is believed to facilitate the fulfillment of dreams and the attainment of salvation from worries and negativities.
In summary, Jyotirlingas are revered as the most sacred representations of Lord Shiva, and millions of devotees visit them every year to worship. Each Jyotirlinga has its own significance and story, making them an integral part of Hindu religious beliefs and practices.
