By definition, non-being ("is not") cannot exist or non-being exists ("is") and, therefore, cannot be non-being.
Nothing lasts. Everything ceases to be.
See short video end of article.
Non-being is inherent in being because every-thing is ultimately no-thing.
The destruction of a thing is the creation of another thing (or things), and visa versa, that is, the creation of a thing is the destruction of another thing.
In the process of destruction and creation, every-thing becomes no-thing, and this no-thing is another thing(s).
In this sense, everything comes from nothing.
Being and non-being are one, being/non-being.
Existence is the process of being/non-being. All reality is process.
No-thing exists. Nothing exists.
Therefore, is isn't.
