Buddhist perspective

 

Buddhism does teach the existence of ghosts through story and imagery, most specifically through what are called, “hungry ghosts.” Hungry Ghosts are used as a metaphor demonstrating that ghosts do suffer through attempting to fulfill earthly desires. It is an exercise in futility, because ghosts find themselves without physical bodies to be able to act out such lusts. The seventh month is believed by many followers of Buddhism to be a time when ghosts and spirits come out of the lower realm and interact with people. So a Ghost Festival of sorts is honored, paying homage to ancestors through various rituals designed to ease the suffering of ghosts and possibly aid in direction. It is believed by Buddhists who celebrate the festival that their ancestors visit them, so it is a time to prepare elaborate meals, ceremonies and offerings to help them in their journey in the afterlife…..
