Wherever you go, there you are

I was thinking about how the phrase "Wherever you go, there you are" is true. But it was hard to find the source of that quote. Actually, if I were to do the research in a library, I would probably find the answer, but I don't have such time. But I found an article that cites The Imitation of Christ as the source, written by Thomas a Kempis.

It would require further research to see if this really is the source of the quote. It's just so common now, it's hard to tell where it came from.
