Appearance of Sharabha
The Sharaba form of Shiva was the structural blend of human, animal
and bird with gigantic as well as blistering look. It had so many
hands, claws and legs, and almost resembled a huge dragon. The
entangled tresses in the body highlighted the ferocity of the
structure to a greater extend. In the head there was a massive crest
which looked like a dome. There were well spread wings on the back
side of the body with a long tail. The extremely sharp incisors in the
mouth and inflexible claws were its main weapons. Its thunder like
voice created echo in the environments and was horrible to hear. It
had three eyes which were glowing like fire balls. Its teeth and lips
were well formed and can be seen properly. It produced awful hissing
Shiva Purana describes Sharabha as thousand-armed, lion-faced and with
matted hair, wings and eight feet. Sharabha Upanishad portrays
Sharabha with two heads, two wings, eight legs of the lion with sharp
claws and a long tail. Kalika Purana describes Sharabha as black in
colour, with four feet downwards and four feet uplifted, with an
enormous body. It also has a long face and nose, nails, eight legs,
eight tusks, a cluster of manes, and a long tail. It jumps high
repeatedly making a loud cry. At first Lord Shiva send Veerabhadra and
asked Narasimha to cool down. But Narasimha ignored his appeal. So he
created Sarabha which outclassed Narasimha both in structure and
power. Then Sarabha lifted Narasimha with its long tail and was about
to throw him. Narasimha realized this and prayed Sarabha to forgive
him. This made Lord Siva to aware the recovery of Vishnu from
ferocious nature and hence did not hurt him. As a mark of respect to
Lord Siva, Narasimha removed the skin of lion from his body and
presented to Sharabeshwaramurti. Thus the incarnation as Sarabha by
Lord Siva pacified the Narasimha manifestation of Lord Vishnu. This
embodiment of Siva is referred as Sarabeshawara. In Shiva temples
idols of two Sarabeshwara are found at the entrance of sanctum.
