Why is Ravana not burnt but worshipped on Dussehra in MP's Mandsaur?

In Madhya Pradesh's Mandsaur, people worship Ravana instead of burning his effigies on Dussehra. Mandsaur is believed to be the birthplace of Mandodari, Ravana's wife, making him the region's son-in-law. For this reason, people offer prayers to Ravana, and a 35-foot statue stands in his memory. On Dussehra, people mourn his death instead of celebrating his defeat.
