The custom of offering food, perfume, or incense, to the dead exists among Hindus and Muslims. If someone comes to see us and we set food before him, or whatever may please him, it is appreciated. It is so with the dead also. They enjoy by our eating, by our smelling the perfume, because, although they do not enjoy the actual thing that we put upon the table, yet the impression of our mind, the joy it gives, mirrors itself upon their soul.
