It is believed that Lord Shiva first manifested himself as a Jyotirlinga on the night of the Arudra 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.
