The creator, preserver and destroyer of all living beings Lord Shiva, is the Supreme God of Hindus. Followers of Lord Shiva are known as Shaivites or Shaivas and they worship Lord Shiva in the form of lingam. For Hindus and Shaivites "12 Jyotirlinga" or "Dwadasa Jyotirlinga" of Lord Shiva are very auspicious. Jyotirlinga is a Sanskrit word, which is a combination of two words- Jyoti (radiance) and linga. Siva Mahapurana or Shiva Purana has a mention of about 64 Jyotirlinga shrines in India and Nepal. Out of 64, only 12 are considered as most sacred and have been called as 'Maha Jyotirlinga'. Each Jyotirlinga is considered as a different manifestation of Lord Shiva. It is believed that once Lord Brahma and Lord Vishnu had an argument regarding their supremacy over each other. To balance this, Lord Shiva appeared in the form of a huge pillar of light and asked them to find the ends of this pillar. Brahma lied that he found the end whereas Vishnu accepted his defeat. Following this Shiva emerged from the pillar and blessed Vishnu and cursed Brahma that he won't be worshiped till the end of eternity. Basically ‘Jyotirling’ is this pillar of light and Jyotirlingas are believed to have appeared from this infinite pillar of light that Lord Shiva produced. Hence the 12 Jyotirlingas are worshiped as manifestations of Lord Shiva. In India, three Jyotirlingas are in Maharashtra, two in Gujarat, two in Madhya Pradesh, one Andhra Pradesh, one Jharkhand, one Uttar Pradesh, one Uttarakhand, and one in Tamil Nadu. Adi Shankaracharya, in his Dwadasha Jyotirlinga Strotram, has mentioned 12 Jyotirlingas situated in different parts of India. Here're some interesting facts about these 'Dwadasha Jyotirlinga':
