 Well, the core belief is again one of causation. Germs don't cause anything. Diseases are not passed through germs. Sickness is not passed through heredity, through DNA. I know I'm undoing most of everything that the world believes in the world, but none of this is real. There is no hereditary disease. There is no disease catching germs because it's a projection. It's all a projection. It's just thoughts in the mind. And there's a beautiful line in the workbook of the course. It says, I can be hurt by nothing but my thoughts. If I'm holding on to thoughts of separation, attack thoughts, that's where the virus is. The virus is not in time and space. The virus is those attack thoughts in the mind. The grievance in the mind is the dis-ease, is the unease of the mind. And of course, atonement or the miracle corrects those, basically shows that those are impossible because God didn't create attack thoughts. And God doesn't create grievances and that's what the atonement shows. Be of good cheer. There is no reason for the belief in harm and the belief in attack, the belief in destruction, whether it be war or it be even viruses and even viruses that seem to be catchable, none of those are real. They're all part of a make-believe thought system. And that's what you're really going for. You're going for the clarity of mind.
