A person’s state of consciousness cannot be immediately recognized from the outside. You can’t tell if pain has darkened him. He looks like always. All humans look from the outside first of all simply like humans. In the end, they are all the same.
The grain of rice also always looks the same. With it, too, we cannot tell from the outside whether it carries a lot of pain or security and how much light or how much darkness we add to ourselves by eating it.
