Chapter One: “Dwelling” (Ju) and “Order” (Xu): The Cosmic Coordinates for Establishing Life

Original Text: “Therefore, that in which the gentleman dwells and finds security is the Order of the Yi (《易》之序也).”

1.1 Inquiry: What Constitutes the Gentleman’s “Dwelling” (Ju)$5

In the pre-Qin lexicon, Ju (dwelling) implies far more than mere physical habitation. The Analects state: “The Gentleman does not go without benevolence even for the space of a single meal. He must be so in moments of haste, and he must be so even when overwhelmed by calamity.” (Lunyu, Liren) The “so” here refers to the spiritual anchor where the gentleman dwells.

In ancient times, the world was perceived as a realm of unpredictable chaos. Floods, wild beasts, warfare, and eclipses—everything was in constant flux. Ordinary people (Xiaoren, small persons) lived in fear and confusion, drifting with the currents. What made the Junzi a Junzi was the possession of a spiritual anchor.

Why does the Gentleman require “Dwelling”$6 Because while “motion” (dong) is absolute, “stillness” (jing) is relative. Without the stillness of Ju, one cannot respond to the motion of the world. The Great Learning says: “Where attainment of stillness is desired, there must first be establishment of purpose; where purpose is established, there can be tranquility; where there is tranquility, there can be ease.” (Daxue) The Ju in the Xicizhuan is precisely the manifestation of this “establishment of purpose.”

1.2 In-depth Examination: What Exactly is the “Order of the Yi” (Yi Zhi Xu)$7

Confucius (or his later disciples) provided a striking answer in the Xicizhuan: the place where the Gentleman finds security is not in grand mansions, but in the “Order of the Yi.”

How is Xu (Order/Sequence) Understood$8 The Shuowen Jiezi defines Xu as the eastern and western walls of a house; extended, it means sequence or order. Within the Zhouyi, Xu encompasses three layers of meaning, which must be analyzed according to the pre-Qin cosmological view:

First Layer: The Logical Progression of the Hexagram Sequence (Textual Order). The Xuguazhuan (Commentary on the Sequence of the Hexagrams) demonstrates the cycle from Qian (Heaven) and Kun (Earth) initiating creation, through the generation of things, to Ji Ji (Already Successful) and Wei Ji (Not Yet Successful). This arrangement is not random. From the pure Yang of Qian to the pure Yin of Kun, and then to the nascent life in Tun (Difficulty at the Beginning) and the obscurity in Meng (Innocence/Veiling), the Gentleman perceives the inevitable laws governing the development of all things.
- Evidential Citation: For instance, Zhuangzi, Chapter “Tianxia,” describes the study of the Yi: “The Yi thereby models Yin and Yang.” This order of waxing and waning Yin and Yang allows the Gentleman to understand that “when depletion reaches its extreme, renewal must follow; when blockage is extreme, ease must arrive.” Knowing that one is currently in adversity, but that ease will inevitably follow according to the Xu, one can achieve “security.”
Second Layer: The Hierarchy of Social Ethics (Ritual and Music Order). The Zhou people placed great emphasis on Li (Ritual propriety); Li is Xu. The Zuo Zhuan states: “Measuring length and proportion, weighing capacity and strength... Therefore, the Son of Heaven established the central order, and the feudal lords established their regional boundaries—this was the regulation of antiquity.” (Zuo Zhuan, Yin Gong 11) The Order of the Zhouyi corresponds to the ethical structure of ruler and minister, father and son, husband and wife (e.g., the hexagrams Jia Ren, Family, and Tong Ren, Fellowship). The Gentleman dwells in the Order of the Yi by maintaining his proper station and not overstepping his boundaries or acting recklessly.
Third Layer: The Rhythm of Heaven’s Operation (Cosmic Order). This is the deepest meaning. Ancient peoples established the four seasons and eight solar terms through the observation of celestial phenomena (guān xiàng). The sixty-four hexagrams correspond to the seventy-two hou (periods of five days), reflecting the breathing rhythm of Heaven and Earth.
- Reflection: Why can the Gentleman achieve “security”$9 Because through the Order of the Yi, he is certain that the world is not a field of chaotic violence, but a meticulously ordered system. Since summer follows spring and winter follows autumn in mutual transformation, and life and death are mutually causal, individual honor or disgrace is but one element within this grand order.

Conclusion: “That in which the gentleman dwells and finds security is the Order of the Yi” means that the Gentleman acquires an "ontological sense of security" by internalizing the logic of the Yijing. He no longer fears the uncertainty of the future because he has grasped the algorithm of time.
