The Shivnetras are an almost extinct community which originated from Varanasi in Northern India.
Similar to the Kshatriyas but somewhat more controversial in social context, the Shivnetras are almost extinct today due to the widespread relocation and displacement of the community.
The word Shivnetra translates into Lord Shiva's third eye, and the first Shivnetra is born out of Shiva's third eye as a Syambhu (or self manifested) which largely points out to be the Hindu deity Kartikeyya or Kal Bhairav as the first Shivnetra. Temples which have been closely linked with this community had either Kartikeyya or Kal Bhairav as a sub-deity with Lord Shiva as the main deity. The Mahakaleshwar Temple in Ujjain Madhya Pradesh in Northern India is said to have been a Shivnetra stronghold apart from Kashi Vishwanath Temple in Varanasi, the netras were believed to have been heavily guarded by Aghoris of both Ujjain and Varanasi almost akin to a secret society, until the great migration to South India commenced.
