When I say 'love', the sound comes out of my mouth and hits the other person's ear, travels through this byzantine conduit in their brain, through their memories of love -or lack of love- and they register what I am saying and they say yes, they understand. But how do I know they understand? Because words are inert. They're just symbols. They're dead. And so much of our experience is intangible. So much of what we perceive can not be expressed; it's unspeakable.
