The Essence of the 'Great Treatise A': A Philosophical Inquiry into the Gentleman's Establishment of Life and the Order of the *Yi*
This article deeply interprets the core proposition from the 'Great Treatise A'—'That which the gentleman dwells in and finds peace is the order of the *Yi*.' It examines how the gentleman, by internalizing the Way of Heaven and Earth and utilizing the *Book of Changes* as the foundation for establishing his life, achieves a state of 'auspiciousness without detriment' through observing the images and contemplating the textual explanations, situated within the Pre-Qin context and the Confucian tradition.
V. The Final Word on the Passage
The Xì Cí Xia Zhuàn concludes:
"The Master said: 'He who knows the Way of Change, perhaps he knows the workings of the Spirits!'"
"Zhi bian hua zhi dao zhe, qi zhi shen zhi suo wei hu! (知变化之道者，其知神之所为乎！)"
He who knows the Way of Change—that is, one who understands the principles of transformation by "observing Images and contemplating Words, observing Changes and contemplating Divinations"—perhaps he knows the workings of the Spirits!
"The workings of the Spirits" (Shen Zhi Suo Wei)—in the Pre-Qin context, "Spirit" (Shen 神) does not just mean deities but also the underlying, subtle principles governing the transformation of all things—the force that transcends ordinary human cognition yet undeniably exists and functions.
"Knowing the Way of Change"—this means understanding the laws governing the world's transformations through this method. Reaching this level means one "knows the workings of the Spirits"—not that one becomes a spirit, but that one understands the operational mechanism of the Spirits (the deep principles of the cosmos).
And a person who understands the operational mechanism of the deep cosmic principles will naturally align his actions with these principles, and naturally "Heaven assists him, bringing no harm to anything auspicious."
Therefore, that wherein the Gentleman resides and finds ease is the Arrangement of the Yi; that wherein he delights and contemplates is the Divinations of the Lines. Thus, when the Gentleman resides, he observes their Images and contemplates their Words; when he acts, he observes their Changes and contemplates their Divinations, whereby Heaven assists him, and everything auspicious brings no harm.
This is what is meant.
