A 21-day vrat dedicated to Lord Shiva as Kedareshwara and Goddess Gauri, begun around Deepavali.
Parvati's vow to obtain half of Shiva's form, the Ardhanarishvara. Kept for twenty-one days, with a twenty-one-knot thread worn and worshipped. Concludes on Diwali. Kept mainly by married women.
One meal a day for the duration; a sweet offering at the conclusion.
