There is a temple in Maharashtra named 'Khandoba Temple'. In the temple, people worship Khandoba Mahadev. Who is he?
'Khandoba Mahadev' is a form of Shiva worshipped to around Maharashtra. He is a kuladevata, or a local deity, and a look through the old census records show that nearly every Maharashtrian family listed him as one of the gods to whom they prayed. Since he's a local deity, he doesn't actually appear in any original texts, so there aren't any primary sources for this, though there is an extensive Wikipedia article about him.
