A decorated thali is a very important component for performing the Karva Chauth puja. A puja thali, also known as Baya, containing the roli, vermilion, sacred water, dry fruits like almonds, pishta etc., earthen clay pots, diyas and different types of Indian sweets, in their respective katoris, is tastefully decorated. The art of creating attractive thalis for puja may also contain the ritualistic decoration like rangoli and alpana. Puja thali can be decorated with floral designs with the help of flowers, leaves, color and also with multicolored pulses.
On this auspicious day, Ma Gaura or goddess Parvati is worshiped. Married women sit around Gaura ma and pray to her for the well being and long life of their husbands. A small pitcher or Karva with some water is placed in the center. While the story is being narrated, ladies circulate their decorated Baya thalis. After the puja, this thali is given to the eldest member of the family who blesses the woman with all the happiness in life.
