Sudasha Brata, or Sudasa Vrata, is a unique ritual observed in Odisha. When there is a rare combination of Shukla Paksha (waxing phase of moon), Thursday and Dashami in Oriya Calendar Sudasha Brata is observed. Sudasa Brata is dedicated to Goddess Lakshmi.
Sudasha Brata is observed mainly by women for the wellbeing of the family. The main ritual involves the tying of a sacred thread on the hand by women. The thread is only replaced during the next Sudasa Vrata.
Special food items like Manda Pithas are offered to Goddess Lakshmi on the day.
Another Sudasha Vrat that is part of the culture of Eastern India is observed during the Dasami day in the Shukla Paksha of Bhadra month by some communities.
