Tonsure
Shaving part or all of the head as a sign of religious devotion or entry into a religious order.
Tonsure is the religious shaving of the head, in whole or in part. Christian monks once wore the Roman tonsure, a shaved crown with a ring of hair, and the Celtic and Eastern forms differed; the Catholic Church stopped requiring it in 1972. Buddhist monks and nuns shave the whole head. In Hinduism, tonsure is offered to deities at temples such as Tirumala and Palani, and performed for children's first haircut and for mourning.
