A Critical Analysis of 'Shen' and 'Zhi' in the Core Passages of the Guanzi's 'Nei Ye' and an Inquiry into Pre-Qin Theories of Mind and Nature
This paper offers an in-depth interpretation of the central passage in the *Guanzi*'s 'Nei Ye'—'That which can transform one thing is called *Shen* (Spirit/Divine); that which can change one affair is called *Zhi* (Wisdom)'—systematically reviewing the philosophical concepts of *Shen*, *Zhi*, *Jing* (Essence), *Qi* (Vital Force), and the *Dao* in the Pre-Qin period to elucidate their pivotal role in self-cultivation and the integration of inner sageliness with outer kingship.

Section 4: Correspondence between the Sixteen-Character Heart Transmission and the Neiye Chapter
Finally, let us return to the most famous dictum on mind cultivation in Chinese intellectual history—the "Sixteen-Character Heart Transmission" from the Shangshu, Dayu Mo:
"The mind of man is perilous and subtle; the mind of the Way is subtle and minute. Be exact, be one, and correctly hold the Center." (Rén xīn wéi wēi, dào xīn wéi wēi, wéi jīng wéi yī, yǔn zhí jué zhōng.)
These sixteen characters highly resonate with the spirit of the Neiye chapter:
- "The mind of man is perilous and subtle" (Human mind tends to deviate from the correct Way, thus requiring cultivation) → "If the Form is not upright, Virtue will not arrive. If the Center is not still, the Mind cannot be governed."
- "The mind of the Way is subtle and minute" (The mind of the Dao is subtle and hard to perceive, requiring careful realization) → "The Dao fills the world, universally present among the people, yet the people cannot know it."
- "Be exact, be one" (The key to cultivation lies in Essence and the One) → "Essence will come on its own," "Adhering to the One without loss."
- "Correctly hold the Center" (Truly upholding the Way of centrality and impartiality) → "Governing the mind resides in the Center," "Rectify the mind within the Center."
From the heart-teaching of the ancient Sages Yao, Shun, and Yu, to the statecraft of Guan Zhong in the Spring and Autumn period, to the Daoist discussions of the Warring States era, the spirit of "Be exact, be one, and correctly hold the Center" runs continuously through. The Guanzi, Neiye chapter is a crucial link and outstanding representative of this spiritual tradition.
