Kannappa
Updated: Wikipedia source
In South Indian traditions, Kannappa was a devotee of the Hindu god Shiva. His story is closely connected with the Srikalahasteeswara Temple in Andhra Pradesh. He is one of the 63 Nayanmars in the Tamil Saiva Siddhanta tradition. Originally a hunter, Kannappar offered his devotion to a shiva lingam by making simple offerings and eventually sacrificing one of his eyes. As he prepared to offer the second, Shiva appeared from the linga, granting him liberation.
