Naga Chaturthi Osha is a fasting observed by women in Orissa
and is held on the 14th day of the bright fortnight of Kartik (September-October).
This fast is mainly observed by women to protect the family members from snake bite. Lord Pingala, serpent god, is worshipped in the form of a snake image. The image is made of gold, silver or of rice paste close to an ant-hill.
