that you were asking 'definition' {merely} of *that* which:
some folks spend an entire lifetime either Trying to discover, convincing others that they Have discovered, correcting others.. who have decided that *their experience* is the Same as [this word symbol]. Or - using this word to sell, convince not-to ... and a few hundred other personalized tangents.
ie. perhaps the #1 Most-Abused English Word of ALL (with the possible exception of the phrase, "Hey.. I'm Honest..")
*Reality*.
Fortunately that wasn't your quest. As to your actual question: IMO that answer is - what they said above, and you suggested.
