In Thirubuvanam near Kumbakonam there is temple in which Sarabeswarar has a huge sannadhi I was there recently This God is in the form of winged lion more powerful than lion & elephant. I gathered that this is a form of Shiva (Avatar) taken to neutralize Narsimha after the later killed Hiranyakasyabu. Does Shiva take avatar? I was under the impression only Vishu takes Avatar. Correct? Jambu
