Zen: a Word that Cannot be Translated

I realized today that I love "zen" as a concept for much the same reason that I love "zen" as a word.  It is a word that cannot be translated.  Similarly, it is a concept that cannot be explained.  It's this perfectly unique, mental, philosophical, and even physical, key.  Thinking beyond thinking.  Would love to write more on this, but tons of work to be done.
