People who are in a position of finding out that they're at risk for some illness, whether it's breast cancer, or heart disease, are afraid to get that information - even though it might be useful to them - because of fears that they'll lose their health insurance or their job.
Reality, for all intents and purposes, is just life - the real world, pure and uncut, shot straight to the vein of our souls every day we draw breath. Whether it's good or bad, it's still reality; the opposite of illusion, the foe of fantasy, and the anchor that keeps us stuck on this plane. And thank Buddha it does, because some people need it in huge doses.
