I'm not sure which is yin and which is yang, but the idea is that in life we are always met with balance in the form of contrasts: good and evil, dark and light, easy come - easy go, you get the idea. I always feel like there is more going on when I am met with evidence of this phenomenon, a deeper meaning, a lesson, or that it will at least all make more sense a bit further down the road.
There must be more to this incident that will come to light at some point. At any rate, I am turning my car in today for repairs and will be without it for several days. The car is just a thing, of course, but it does afford flexibility and convenience which I will be doing without for a short while (we forgot to add rental reimbursement to our insurance when we sold our jeep). So this episode of yin and yang lessons may not be over. I will keep my eyes open for clues to the greater meaning of this during my small season of inconvenience!
