Varuthini Ekadashi, also known Baruthani Ekadashi, is a Hindu holy day, which falls on the 11th lunar day (ekadashi) of the fortnight of the waning moon in the Hindu month of Chaitra (per the South Indian Amavasyant calendar, every month ends with a new moon) or Vaishakha (per the North Indian Purnimant calendar, every month ends with a full moon).
[4] The greatness about Varuthini Ekadashi is narrated by the Hindu deity, Krishna, to King Yudhishthira in the Bhavishya Purana.
One should keep an all-night vigil, praying to God, singing devotional songs and hymns in the company of family members.
[5] The Havishyanna food (boiled food without spices, salt and oil) offered to the yajna (fire sacrifice) on the previous day (10th lunar day - Dashami) should be consumed by the people observing this fast.
[6][4][3] Following all these rules on Varuthini Ekadashi is believed to usher prosperity, name and fame to the individual in the society.
