A Jyotirlinga or Jyotirling or Jyotirlingam is a shrine where Lord Shiva, an aspect of God in Hinduism is worshipped in the form of a Jyotirlingam or "Lingam of light." There are twelve traditional Jyotirlinga shrines in India.
It is believed that 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.
