Smoke test --- 12 Jyotirlingas of Lord Shiv
A Jyotirlinga or Jyotirling or Jyotirlingam (Sanskrit: ज्योतिर्लिङ्ग) are shrines where Lord Shiva, is worshipped in the form of a Jyotirlingam. ‘Jyothi’ means ‘Radiance’ and Lingam, the Shiva Lingam-‘the mark or sign’ of The Almighty or the phallus symbol. Jyotir Lingam means the The Radiant sign of The Almighty. There are twelve traditional Jyotirlinga shrines in India.
Lord Shiva first manifested himself as a Jyotirlinga on the night of the, Aridra Nakshatra thus the special reverence for the Jyotirlinga. There is nothing to distinguish the appearance, but it is believed that a person can see these lingas as columns of fire piercing through the earth after he reaches a higher level of spiritual attainment. There are twelve Jyotirlingas in India and they are spread all over India.
As per Shiv Mahapuran, once Brahma (the God of creation) and Vishnu (the 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.
