The tonsure, or Mundan Sanskar, purifies a child from prior birth sins and negativities, according to Hindu tradition. After going through 84 lakh Yonis, a soul takes on a human body, with each Yoni having a different impact on human birth. Shaving a baby's head cleanses him or her of past crimes and frees him or her from all negative consequences. Mundan Sanskar is a highly essential Karma in boosting a child's wisdom, health, age, strength, and agility, according to Yajurveda.
