As per Shiv Mahapuran, once Brahma (the Hindu God of creation) and Vishnu (the Hindu God of preservation) had an argument in terms of supremacy of creation. To test them, Shiva pierced the three worlds as a huge endless pillar of light, the "jyotirlinga". Vishnu and Brahma split their ways to downwards and upwards respectively to find the end of the light in either directions. Brahma lied that he found out the end, while Vishnu conceded his defeat. Shiva appeared as a second pillar of light and cursed Brahma that he would have no place in ceremonies while Vishnu would be worshipped till the end of eternity. The "jyotirlinga" is the supreme partless reality, out of which Shiva partly appears. The "jyothirlinga" shrines, thus are places where Shiva appeared as a fiery column of light. Originally there were believed to be 64 "jyothirlingas" while 12 of them are considered to be very auspicious and holy. Each of the twelve "jyothirlinga" sites take the name of the presiding deity - each considered different manifestation of Shiva. At all these sites, the primary image is "lingam" representing the beginningless and endless "Stambha" pillar, symbolizing the infinite nature of Shiva. The twelve "jyothirlinga" are Somnath in Gujarat, Mallikarjuna at Srisailam in Andhra Pradesh, Mahakaleswar at Ujjain in Madhya Pradesh, Omkareshwar in Madhya Pradesh, Kedarnath in Uttarakhand, Bhimashankar in Maharashtra, Viswanath at Varanasi in Uttar Pradesh, Triambakeshwar in Maharashtra, Baidyanath at Deoghar in Jharkhand, Nageswar at Dwarka in Gujarat, Rameshwar at Rameswaram in Tamil Nadu and Grishneshwar at Aurangabad in Maharashtra.
