Guiguzi's 'Nourishing the Will by Emulating the Numinous Turtle': A Deep Interpretation of Archaic Wisdom
This article undertakes an in-depth exploration of the proposition 'nourishing the will by emulating the numinous turtle' (yang zhi fa ling gui) in the Guiguzi, examining the symbolic significance of the turtle in high antiquity, the wu-xi shamanic tradition, turtle-shell divination culture, ritual status, and longevity philosophy from multiple dimensions, revealing the profound philosophical thought and methodology of spiritual cultivation it embodies, and striving to restore its original meaning within the pre-Qin intellectual context.

Supplementary Discussion: On the Question of Authenticity of the Guiguzi's "Seven Chapters of the Root Canon of Hidden Talismans"
The question of the date of composition and authorship of the Guiguzi has long been debated in scholarship. The "Seven Chapters of the Root Canon of Hidden Talismans" in particular have been questioned -- some scholars believe these seven chapters were later additions, not original works of Guiguzi.
However, this debate does not affect the thesis of this essay, for three reasons:
First, even if the "Seven Chapters of the Root Canon of Hidden Talismans" were not written by Guiguzi himself, the intellectual content is deeply rooted in the soil of pre-Qin thought. The archaic turtle divination tradition, the pre-Qin masters' discussions of "will," the Daoist cultivation of empty stillness, and the strategic thought of the military theorists discussed in this essay are all firmly attested pre-Qin material, unaffected by the question of the Root Canon's authenticity.
Second, the proposition "nourishing the will by emulating the numinous turtle" is highly consistent with and mutually corroborated by the Yijing's canonical text on "abandoning the numinous turtle" and the pre-Qin masters' discussions of "will," "turtle," and "numinous." Even if the verbal formulation of this proposition was composed by a later hand, its intellectual substance is inherent in the pre-Qin tradition.
Third, the purpose of this essay is not to investigate the authenticity of texts (that is the task of philology) but to interpret the meaning of ideas. The value of ideas is neither increased nor diminished by certainty or uncertainty about authorship.
Therefore, this essay treats "nourishing the will by emulating the numinous turtle" as a pre-Qin intellectual proposition for interpretation, without engaging in debates about its textual attribution.
