The difference between knowledge and experience is inexpressible. In life, you experience the positive and negative aspects and nuances, including defamation, rejection, aloneness, racism, and prejudice of every kind. Then, finally, you come to what can be described as an elevated spiritual and neutral place. This sounds simple, but it will take many, many lifetimes to get it right. All white entities come down in a white column of light.
All dark entities come down in darkness.
This makes it very easy for us. Of course, even with our intelligence, we're not always aware of who's dark and who's light, unless we see them coming into being. It would be nice if you had eyes that were open in which you could look around a place and see those with a dark column or a white column. It would be much easier for you to differentiate between them, but most of you cannot do this. The main purpose of life is to help other people combat the darkness that confronts them.
