Looking at the slightly puzzled crowd, Zhang Yuan recalled the feeling from that time and said, "Without experiencing it firsthand, it's really hard to describe."
"To give a concrete example, everyone has two eyes and possesses normal vision. But what about blind people? Some might think that blind people can't see the world, so they must see blackness, like when we close our eyes, but it's actually not like that... That blackness is just the color produced when light is blocked by our eyelids."
"What is the true sensation for blind people then?"
Zhang Yuan blinked his own eyes and explained, "Everyone just open your left eye and close your right eye. What the closed eye feels is what blinds people sense; it isn't blackness, but a state of emptiness."
Yes, emptiness.
With that explanation, nearly everyone understood.
"Emptiness" is a very abstract concept, but it undeniably exists. It's as if there's nothing at all, as if the brain has directly lost that closed eye.
