The Legend of Mahabharata

The belief in this fast and its associated rituals goes back to the preMahabharata times. Draupadi, too, is said to have observed this fast. Once Arjun went to the Nilgiris for penance and the rest of the Pandavas faced many problems in his absence. Draupadi, out of desperation, remembered Lord Krishna and asked for help. Lord Krishna reminded her that on an earlier occasion, when Goddess Parvati had sought Lord Shivas guidance under similar circumstances, she had been advised to observe the fast of Karva Chauth. In some tellings of this legend, Shiva tells Parvati the story of Veervati to describe the Karva Chauth fast. Draupadi followed the instructions and observed the fast with all its rituals. Consequently, the Pandavas were able to overcome their problems.
