Overview
Raja Parba, also known as Mithuna Sankranti, is a three-day-long festival of womanhood celebrated in Odisha, India. The second day of the festival signifies beginning of the solar month of Mithuna from, which the season of rains starts.
Mythology
It is believed that the mother Goddess Earth or the divine wife of Lord Vishnu undergoes menstruation during the first three days. The fourth day is called Vasumati Snana, or ceremonial bath of Bhudevi. The term Raja came from the Sanskrit word 'Rajas' which means menstruation and when a woman menstruates, she is called 'Rajaswala' or a menstruating woman, and in medieval times the festival became more popular as an agricultural holiday marking the worship of Bhudevi, who is the wife of lord Jagannath.
A silver idol of Bhudevi is still to be found in the Puri Temple beside Lord Jagannath .
Rajaparba
It falls in mid June, the first day is called Pahili Raja,
second day is Mithuna Sankranti, third day is Bhudaaha or Basi Raja.
The final fourth day is called Basumati snana,
in which the ladies bath the grinding stone as a symbol of Bhumi with turmeric paste and adore with flower, sindoor etc. All type of seasonal fruits are offered to mother Bhumi.
The day before first day is called Sajabaja or preparatory day during which the house, kitchen including grinding stones are cleaned, spices are ground for three days. During these three days women and girls take rest from work and wear new Saree, Alata, and ornaments. It is similar to Ambubachi Mela.
The most popular among numerous festivals in Odisha, Raja is celebrated for three consecutive days. Just as the earth prepares itself to quench its thirst by the incoming rain the unmarried girls of the family are groomed for impending matrimony through this festival. They pass these three days in joyous festivity and observe customs like eating only uncooked and nourishing food especially Podapitha, do not take bath or take salt, do not walk barefoot and vow to give birth to healthy children in future. The most vivid and enjoyable memories one has of the Raja gaiety is the rope-swings on big banyan trees and the lyrical folk-songs that one listens from the nubile beauty enjoying the atmosphere.
