Our world today is very Yang with lots of rushing to and fro, 24/7 energy output, little sleep and rest ... and the list goes on.

Much ado is made about Yang energy, and it is well rewarded monetarily. Not so with the Yin.

Sleep is Yin, and getting enough sleep is considered a sign of weakness; going slowly, whether on foot or auto, is considered aberrant. The Yin is nowhere to be found.
