How is Chhath Puja linked to the Puranas?

The Prakriti Khanda of the Brahmavaivarta Purana is considered the primary scriptural source for the origin of Goddess Shashthi, popularly worshipped as Chhathi Maiya during the four-day Chhath festival. She is described as the mind-born daughter of Lord Brahma, and the wife of Kartikeya, and is traditionally known as Devasena. Chhath will be celebrated from November 13 to 16.
