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.

III. "You means to help"
"Aid (You)" means help. "Heaven assists him" (Zi Tian You Zhi) means help coming from Heaven.
However, we must pay attention to the character Zi (自). Zi can be interpreted as "from" (from Heaven assisting him), meaning Heaven helps him; or it can be interpreted as "self" (Heaven assists him through himself), meaning his own actions elicit Heaven's aid.
Both interpretations have merit, but given the overall context of the Xì Cí Zhuàn, the second interpretation is more appropriate—the Gentleman’s actions (observing Images and contemplating Words, observing Changes and contemplating Divinations, treading on trustworthiness, contemplating compliance, and honoring the worthy) elicit Heaven's assistance, rather than Heaven bestowing blessings for no reason.
This aligns with the spirit of the Book of Documents, Tai Jia:
"If Heaven brings disaster, it can still be avoided; if one brings disaster upon oneself, one cannot escape."
Heaven's calamity may perhaps be averted, but one's self-inflicted calamity cannot be escaped. Similarly, Heaven's assistance does not arrive without cause but is inspired by one's own virtue.
