Kūkai's Bodily Absorption and Modern Scientific Philosophy — A Rigorous Analysis from the Self-Referential Mind-Field to T⁶⁴ Sectional Projections

Kūkai (Kōbō Daishi) entered meditative absorption in 835 CE; his body remains incorrupt to this day and receives daily homage from devotees at Okunoin on Mount Kōya. Traditional Buddhist scholarship has offered doctrinal interpretations of this phenomenon, yet a dialogue interface with modern scientific philosophy has been lacking. While preserving the depth of Buddhist textual research, the present paper introduces the cognitive framework of Yuanxian Theory: 1. defines a “section” as a projection operator \(πσ\) on the fibration of \(T⁶⁴\);2. clarifies the subordination relation between \(Ψ*\) and \(T⁶⁴\): \(Ψ*(F)\), where \(F\) is the self-referential operator on \(T⁶⁴\);3. restricts “immutability” to the axiomatic layer, leaving derivative analyses open to future empirical evidence. **Core claims**: - Bodily incorruptibility is not “material structure that has not decomposed” — it is the steady-state manifestation of \(Ψ*\) after self-referential closure has been completed on the “bodily section”.- The “spiritual-information energy field” is not “another kind of field” — it is the self-inspection phase structure of \(Ψ*\) on the latent-phase section.- The six supernormal powers are not “supernatural abilities” — they are projection readings of \(Ψ*\) on six specific sections. --- 空海(弘法大师)于公元835年入定,至今肉身不坏,每日于高野山奥之院接受信徒顶礼。这一现象在传统佛学研究中有教理层面的阐释,但始终缺乏与现代科学哲学的对话接口。 本文在保持佛学研究文献深度的基础上,引入元宪理论的认知框架: 1. 将“截面”定义为 \(T⁶⁴\) 纤维化上的投影算子 \(πσ\);2. 明确 \(Ψ*\) 与 \(T⁶⁴\) 的从属关系:\(Ψ*(F)\),其中 \(F\) 是 \(T⁶⁴\) 上的自指算子;3.
