According to Ganesha-Purana, Ganesha had ridden onto a peacock to kill a Danava called Sindhu. In Morgaon the same Mayureshwara avtara can be seen, who is also called Moreshwara. It is also said that only after worshipping Moreshwara, Vamana and Parvati were blessed with a baby boy. They named him Morya. Morya was a Ganesha devotee from his childhood. He even went to Theur and rigorously worshipped Ganesha, so much that he actually felt the divine presence of His. From then on he was called Moroba Gosawi or simply Morya.
Moroba deeply studied Veda-Vedanga, Purana, Upnishads. He made an Ashrama for himself in Chinchawad near Pawana river of Pune. Legend has it that even Samarth Ramadasa and Sant Tukarama used to pay visit to him in his Ashrama. Samartha Ramadasa had written his famous Ganpati Vandana “Sukhkarta-dukhharta Varta Vighnachi” in this very Chinchawad ashrama. The festival of Ganesha Chaturthi is ceremoniously celebrated at the Morgaon Ganesha temple even since the times of Morya. Moreshwara is also the first departure point of Ashtavinayaka Yatra.
