So I will write down a thread about a similar kerala religious observation called #ThiruvathiraNoyambu or Thiruvathira fasting.
Observed mainly by unmarried girls for getting a husband like #Mahadev & married women for the longevity of their spouse
Women& girls observe fasting on Thiruvathira for the wellfare of their husbands and would-be husbands. Mothers also observe fasting on the day before for the wellbeing of their children. Ritual fasting meant abstaining from all rice-based food.
Women celebrating Thiruvathira spent the rest of the day participating in various festive activities.
At night, the women stayed awake& performed #Thiruvathirakkali, a hand clapping folk dance. The lyrics of these songs revolve around Parvathi’s love 4 Shiva
