There's a difference between «nothing» and no thing

[Edvard]

- Eckhart Tolle

He goes on: «Nothing is simply denial. But no thing means there's a presence there, but it has no form. Nothing that you can grasp. There is no shape and no thought and no name. The ancient Chinese call it the Dao; which cannot be named. (...) The Dao that can be named or spoken of is not the true Dao.»

I watched this video yesterday! Eckhart is enlightened beyond words!

Yeah, nothingness and emptiness are words that can easily confuse, or even scare people. There isn't nothing. There is simply no thing. 
You only use the word nothing because you though there were things in the first place.
I do kind of like the word no-thing-ness though. But these words kind of fall flat eventually because they first have to point to an illusion in order to describe truth.
