I hope this encourages you to continue thinking about Yin-Yang from various perspectives. Considering Yin-Yang from different viewpoints can be a truly fascinating process. The concept of Yin-Yang is not just philosophical but deeply connected to our daily lives and natural phenomena. From this perspective, you may gain new insights through the changes and harmony of Yin-Yang.
For a deeper understanding of Yin-Yang, observe the objects and phenomena around you in your daily life. For example, looking at the changes of seasons, the cycle of day and night, and the changes in emotions from the perspective of Yin-Yang can be a good method.
