"The Purpose of Cremation: After death, Hindus are not buried, but cremated. The idea is that the human personality is made up of five elements of which four belong to the body and come from this world, namely fire, earth, water and air while the fifth the ether (fine matter) belongs to the domain of the subtle body and comes from the higher worlds. By cremating the body, the elements are rightfully returned to their respective spheres, while the subtle body along with soul returns to the worlds beyond for the continuation of its afterlifeThe Purpose of Cremation: After death, Hindus are not buried, but cremated.
