Interaction - 相互作用 - Xiānghù zuòyòng
Reality cannot escape the boundaries of the mind.
Life is made real through thoughtful projection;
sensation springs forth
This world is meaningless, if we do not interact with it. Rocks are rocks, plants are simply plant matter; these things appear to have no significance to us. But if we decide to make the rock a votive object, or we choose to venerate a tree, then these objects acquire great importance. To an outsider, who does not know the holiness of these items, then the rock will still just be a rock. The tree, just a tree. In all cases, the line of thinking was correct. Only through human interaction is meaning created.
It is a mistake to assume that the meaning that is given to something is as concrete and tangible as the object itself. This can lead to confusion, as there is a separation between physicality and essence. The house you grew up in may be precious to you, but to many of us, it is simply a building that housed a family. To you, that is the source of every childhood memory, providing a home to sentiment and sincerity. If you lose the house, your feelings are much more likely to dictate your response than your reason. Your emotional perspective is more likely to determine the sense of loss than the monetary value of the house.
Since perception of reality is subjective, some schools of philosophy suggest a perspective which sees everything, life included, as unreal. By contrast, followers of Tao should maintain a constant connection with the world. Interaction is a integral component to altering reality. If you do not take initiative, to work within the system of projected meaning and echoed essences, then you will fall into dormant hibernation, and the world will not exist. As long as you remember that the meaning attributed to objects is subjective, coming from within, then you will be able to avoid mistakes.
This world is truly what we make it.
