Sometimes transliterated as: Kesavapaniya, KeZavapaniya, Keshavapaniya
Keśavapaniya literally means ‘hair-shaving ceremony’.
Great kings and emperors used to perform the Rājasuya sacrifice. As one of the vows, they were expected not to cut the hair on the head or shave the beard for one year after the Daśapeya rite. This rite was a part of the bigger sacrifice. The ceremonial shaving of the hair after one year was known as ‘keśavapaniya’.
