The veneration of the dead, including one's ancestors, is based on love and respect for the deceased. In some cultures, it is related to beliefs that the dead have a continued existence, and may possess the ability to influence the fortune of the living.

However, in other cultures, this act of worship does not confer any belief that the departed ancestors have become some kind of deity. Rather, the act is a way to express filial duty, devotion and respect and look after ancestors in their afterlives as well as seek
