8th Sanskar of the 16 Hindu Sanskar is Mundan Sanskar, also known as Chudakarana. It is a Hindu ritual performed on a child's first haircut, usually between one and three years of age. It is considered a purification ceremony to shed negative energy from past lives, protect from evil forces, and promote physical and spiritual well-being. The ceremony involves a priest chanting mantras, the head being shaved, and the hair being offered to a deity or river, followed by feasting and celebration.
