There is a divine idol of Ganpati present at the Swayambhu Ganpati Temple that is made of pule, which is nothing but white sand and is believed to be self originated - it is not manmade. Another idol of Ganpati which is made of copper is placed in the Sanctum Sanctorum. It depicts the Lord astride on a lion. The idol is so set that at sunrise and sunset the golden light of the sun penetrates and enlightens the idol.
The distance of Swayambhu Ganpati Temple from the city of Ratnagiri is nearly 20 km. The enchanting beats originating from the nagaras are so pure and can be heard in the early morning. In the evening, you can hear the chaughadas rhythms at the time of changing the clothes of the idol.
