Heaven-and-Earth is not sentimental;
It treats all things as straw-dogs.
The Sage is not sentimental;
He treats all his people as straw-dogs.
Between Heaven and Earth,
There seems to be a Bellows:
It is empty, and yet it is inexhaustible;
The more it works, the more comes out of it.
No amount of words can fathom it:
Better look for it within you.
This is a beautiful chapter that conveys so much wisdom in so few words.
I want to begin by pointing out something at the very beginning of the verse: “Heaven-and-Earth” is hyphenated, implying that it is a single entity and not something dualistic. We can interpret this as a symbol for ourselves, a combination of the spiritual and the physical combined into one being. The concept is also incorporated into the yin and yang symbol, where the two seeming opposites are actually part of the whole.
In the second stanza, we are introduced to the “Bellows” which exists between Heaven and Earth, meaning it exists within ourselves and serves as the boundary/connector between the physical and the spiritual. The Bellows is the source of breath, which is Qi (or Chi) and it the life energy that flows through us and is associated with breathing. The practice of Tai Chi improves breathing and helps practitioners connect with their life energy. The more that you practice conscious breathing, the more connected to your life energy you become, as is expressed in the line, “The more it works, the more comes out of it.”
This life energy is ineffable: “No amount of words can fathom it.” Because it exists in a space between the physical and the spiritual beings, essentially connecting the two, it cannot be expressed in words. It is beyond our comprehension.
Finally, we are entreated to search for this source within ourselves. This is the path of the Tao and the way to become a sage: to search for this source of life energy within each of us, connect with that energy, and allow it to flow freely through us.
