It's not that simple, depending on the Mandarin writing it can also refer to "essence" and probably some other things.

It's appearing in traditional Chinese medicine and seems to be a fairly important concept there.

It also seems to be used as a name.

So Jing is a fairly wide spread well known mandarin word but a Jing + OS + wrong pronoun-cation sounds similar to a not that widely known english word which seems to have gone out of fashion quite a while ago...
