"If you are aware of a state you call “is”, or reality, or life, this implies another state called “isn’t”, or unreality, or nothingness, or death.
There it is. You can’t know one without the other.
And so, as to make life poignant, it’s always going to come to an end.
That is exactly, don’t you see, what makes it lively.
Liveliness is change, is motion. You’re always either at apoint, or you aren’t."
