Hair and prassad
Tamil Nadu,
India
Shaving of heads is a symbolic gesture for a Hindu either done as gratitude for fulfilling a wish/prayer, or after the death of an elder member of the family hair is offered to the gods, representing a real sacrifice of beauty, hence shaving your head shows your grief for the departed soul.
Prassad is normally sweet rice or semolina and is given by the brahmins to devotees.
