Yin and yang can be hard to reconcile. The only reason that nature has managed to combine them is that this was necessary for it to exist at all, since neither yin nor yang can exist by themselves in any form at all. It was needed for nature to achieve this balance between yin and yang in order for it to be able to evolve at all. We must be cautious to retain this balance.

Yin and yang cause one another; yet at the same time, they also avoid one another, as night shuns day and day shuns night. Try at all times to be mindful to be balanced between the two. Do not fear sadness when you are in joy, and do not fear joy when you are in sadness, but try to accept that one flows into the other as day and night. There can be joy in sadness and sadness in joy, and neither is above the other.

As our species are more yang than yin, we tend to fear sadness rather than joy, even though, when our joy remains too long, it will turn into anxiety. Some who are in sadness, on the other hand, fear joy when it comes to them. Try to accept both. Do not deny your sadness, but neither deny your joy. We must accept it when one has to succeed the other. The same counts for all things yin and yang, such as work and rest, or society and solitude.
