Arawa-Arwaine is being observed Wednesday in the first day of the Chhath event, a festival of cultural and religious importance in Nepal.
Arwa-Arwaine is also considered the day to take a dip to cleanse the body. Begining with rigorous fasting on Kartik shukla panchami, the devotees go to nearby rivers & ponds & worship the setting sun. Then, they worship the rising sun with special respect and conclude the festival.
The Chhath is celebrated in the ancient Mithila's capital, Janakpurdham with fanfare wishing longevity of the progeny.
It is considered a incredibly challenging festival requiring devotees to be seated for strict fasting during the two days.
