A Dialectical Analysis of the Tripartite Qualities of 'Dao' in the Guanzi: Intricacy, Expansion, and Solidity
This paper provides an in-depth interpretation of the opening discourse on 'Dao' in the *Guanzi: Neiye*, analyzing the connotations and dialectical unity of its tripartite qualities: 'intricacy necessitates density, expansion necessitates ease, and solidity necessitates firmness.' It further explores their significance for self-cultivation and mental governance within the context of Pre-Qin and ancient thought.

III. Multiple Meanings of "Zheng" (Proper/Upright)
The character "Zheng" (正) in "Once the four limbs are proper" carries extremely rich meanings in Neiye and pre-Qin thought as a whole:
- Bodily Level: Proper, not crooked.
- Psychological Level: Just, unbiased.
- Ethical Level: Upright, not crooked or evil.
- Political Level: Proper, not obscured.
- Cosmological Level: In harmony with the proper Qi of Heaven and Earth.
Guanzi, Neiye, states: "Rectify the mind within, and all things will fall into place." When the mind is proper, all things fall into their proper place—this is the causal chain from the mind's correctness to the correctness of all things.
Laozi, Chapter Forty-Five, states: "Purity and stillness govern the world with correctness." Purity and stillness themselves are correctness—a person whose inner self is pure and still naturally governs the world with correctness.
"Once the four limbs are proper" seems merely a requirement for bodily posture, but it implicitly encompasses comprehensive uprightness from the body to the mind to all things—straightening the body to rectify the mind, rectifying the mind to rectify Qi, and rectifying Qi to rectify all things.
