Magh Pournima Yellamma Renukadevi

Every Magh Pournima of the Hindu calendar is celebrated in the honour of Goddess Renuka, also known as Yellamma devi. In Karnataka, it is known as Bharat Hunvi or BharatHunime. 

Renuka devi is a symbol of ultimate marital sacrifice. Despite being raised a princess she was married to the severe sage Jamadgni, and lived a life of chastity and simplicity. 

Being an incarnation of Goddess Lakshmi, she loves Pooran or Hoorna. So sweets made of hoorna, especially Kadabu, are made on this day.
