MAHADEV AND BHAKTA KANNAPPA/ THINNADU

A couple of Boya caste in Udumooru village of Andhra Pradesh had a son Thinnadu. He was good at archery and was a Shiv Bhakt.
Everyday Thinnadu hunted a wild animal and offered it on a Shivlinga in the forest mandir.

The same Shivlinga was worshipped by a Brahman who was horrified at the way Thinnadu made the blood-smeared offering to Shiva.
One day, when the Brahman was near the Mandir, he saw Thinnadu coming carrying a dead animal in hands and water in his mouth for offering on Shivlinga.

But that day, Thinnadu saw blood oozing out from the left eye on the Shivlinga. He tried to apply forest herbs but blood did not stop. So Thinnadu cut his left eye and placed it on the Shivlinga. Blood stopped immediately.
Now the right eye on Shivlinga started dripping blood.

Thinnadu decided to offer his right eye too but without eyesight he would not know where to place the eye on Shivlinga correctly.
So he lifted his leg and put his toe on the right side of Shivlinga to mark the place where he would put his eye later.

Shiva then appeared n stopped him. The brahman also realised the fierce n true devotion of Thinnadu.
Thinnadu got the name Kannappa Nayanar (he who offered his eye to Prabhu).
The forest Mandir is revered today as Kannappa Mandir, Srikalahasti.

True devotion is selfless love
