Zhuangzi's Nine Truths

1My life is finite, while knowledge is infinite. To pursue the infinite knowledge with a finite life is bound to fail!

Zhuangzi believes that the Dao has a great effect, it is everywhere and can master everything, adapting to nature, achieving harmony with heaven and man, is the ultimate state. Zhuangzi's 'heaven and I are born together, and all things are one' with this spiritual realm is the clearly defined state of 'heaven and man' being one. Therefore, people should return to simplicity and return to the true nature of nature to maintain their perfect humanity and to live in harmony with nature. This is Zhuangzi's cosmology and epistemology, containing a naive dialectical idea.
Zhuangzi believes that if you can achieve 'unity of all things', you will attain the realm of (xiāo yáo - serenity, freedom). This is Zhuangzi's philosophical concept of individual spiritual liberation – living without contradiction in the world. Zhuangzi doesn't deny contradictions, but emphasizes overcoming contradictions subjectively. He uses 'non-action' (wu wei) to explain this concept, which is different from Laozi; 'non-action' here means a state of freedom and ease of mind, without being dragged by external things. In this state, people abandon their pursuit of fame and fortune, ride with the 'rectification of heaven' (heaven's positive qualities) and master the 'six airs' (the six elements/weather), and wander endlessly.
