I can say this is inaccurate from all of my observations. Some spirits that are heavily connected to some cultures might understand the language spoken in those areas. Most spirits from my experience though don't really speak language and might not even interact with humans very often or at all. They tend to communicate through pure ideas and feelings amongst each other and humans. Most practitioners I am aware of use some method to translate that into language. Keep in mind this also does not speak to spirits that were formerly human at one point. Those types of spirits likely remember the language they spoke during life.Does the spirit speak Arabic or Hebrew? Some magic books claim that spirits only speak these two languages. Is this true?
