Hindu legend.
Once Buddhism eliminated from Deccan Plateau region during medieval age, Hinduism started its domination here. As per Hindu legends, due to unavoidable situations and disasters including famines, the natural beauty in this region started dying. Rivers died, forests started to burn due to heat and as its effect, the biodiversity here stated to vanish. Unique birds like the Great Indian Bustard of this region started to vanish. In order to prevent this, the people of the villages started to worship Shiva by establishing a shivalinga inside these caves. Even though after severe efforts, here was relief from famines. After all this, in order to protect its clan, a bustard bird started worshipping the Shivalinga. By seeing devotion of an innocent bird to relieve from the disastrous nature, Shiva appeared before the bird and granted him the boon. Today, the Lord here is worshipped as Ghoradeshwar, which is made of two words, Ghorad and Ishwar. The word Ghorad stands for The Indian Busters in Marathi and Ishwar stands for Lord. The word Ghoradeshwar means Lord of the Bustard.
