Within the depth-psychology and comparative religion corpus represented in this library, Neidan — Chinese 'inner alchemy' — emerges primarily through the comprehensive scholarly apparatus of Livia Kohn's Daoism Handbook, where Pregadio and Skar supply the authoritative account. The corpus treats Neidan not as a unitary system but as a historically stratified complex of esoteric doctrines synthesized from classical Daoist texts, Yijing cosmology, yangsheng disciplines, waidan external alchemy, medical theory, Buddhist soteriology, and Confucian moral philosophy. Central tensions in the literature concern the relationship between Neidan's physical and purely contemplative registers — the 'lower virtue' path requiring disciplined cosmological work versus the 'higher virtue' path rooted in spontaneous wuwei awareness — and the historiographical rivalry between the Zhong-Lü, Nanzong, and Quanzhen (Beizong) lineages. The corpus gives particular weight to the doctrine of the Three Treasures (jing, qi, shen), the role of xin (heart-mind) and yi (creative imagination) in guiding inner transformation, and the graduated alchemical stages culminating in the refinement of essence into breath and spirit. The broader significance for depth psychology lies in Neidan's sustained attention to inner imaginative process, the symbolic transmutation of psychophysical constituents, and the tension between self-conscious cultivation and spontaneous realization.
Neidan or 'inner alchemy' refers to a range of esoteric doctrines and practices that adepts use to transcend the individual and cosmo-logical states of being.
This passage provides the foundational definition of Neidan, tracing its multi-strand origins from classical Daoism, correlative cosmology, yangsheng, waidan, medical theory, Buddhist soteriology, and Confucian moral philosophy through to its codification by the twelfth century.

xin, in fact, is home to the yi or 'creative imagination' which guides and makes possible the joining of yin and yang and the generation and nourishment of the inner elixir.
This passage identifies the heart-mind (xin) and creative imagination (yi) as the operative psychic faculties within the Neidan process, foregrounding the imaginative and contemplative dimensions of inner alchemical transformation.

The first representation is the doctrine of the three treasures (sanbao), namely jing (essence), qi (vital energy/pneuma), and shen (spirit), which are the basic ingredients of the neidan process.
This passage articulates the Three Treasures doctrine as the cosmological and physiological substrate of Neidan, distinguishing between primordial and conditioned aspects of each ingredient and their role in the transformative process.

The way of higher virtue, by contrast, starts with the awareness of the fundamental nature of reality and the human being. It is based on spontaneous, un-self-conscious and non-intervening activity (wuwei), permitting the immediate recognition of the real nature of oneself and the cosmos.
This passage delineates the two-path structure within Neidan traditions, contrasting the self-conscious, cosmologically-guided lower path with the spontaneous, master-transmitted higher path rooted in wuwei awareness.

First stage: 'Refining Essence and Transmuting it into Breath' (lunjing huaqi), also known as the 'Barrier of Hundred Days', cultivates ming and seeks to unify one's essence and breath/energy.
This passage gives a detailed account of the first of Neidan's graduated alchemical stages, describing the microcosmic orbit through which essence is transmuted into breath and the body's energetic circulation is reversed and refined.

The three main neidan legacies that existed between the tenth and fourteenth centuries became known anachronistically as the Zhong-Lü, Nanzong (Southern Lineage) and Beizong (Northern Lineage, more accurately Quanzhen or Complete Perfection).
This passage maps the major institutional lineages of Neidan, explaining how the Nanzong/Beizong terminology was politicized by Ming-era literati to demote the Yuan-patronized Quanzhen tradition in favor of a southern heritage.

The status of this method was further enhanced when neidan came to replace waidan. Thus, the southern lineages which, during the Six Dynasties, produced the alchemical version of the Cantong qi, ultimately led to the decline of waidan, but laid the foundations for the continuation of the arts of the elixirs in new forms.
This passage argues that Neidan's historical ascendancy was achieved through the appropriation and internalization of waidan's cosmological symbolism, particularly via the southern lineages' reinterpretation of the Cantong qi.

The Cantong qi uses an obscure metaphoric structure and an extremely complex terminology to link alchemical processes with various cosmogonic and cosmological patterns.
This passage traces Neidan's intellectual prehistory through the Cantong qi's fusion of alchemical and cosmological symbolism, noting its influence on both Shangqing meditative alchemy and the later emergence of formalized Neidan traditions.

Among the best known figures for their neidan writings in the Yuan were Li Daochun, his disciple Miao Shanshi of Jiangsu and Chen Zhixu of...
This passage documents the Yuan-dynasty proliferation of Neidan authorship and the interpenetration of northern Quanzhen and southern contemplative-exorcistic traditions within the broader Neidan textual heritage.

The boundary between waidan and neidan becomes very subtle in one of the main Song texts on alchemical theory, the Danfang aolun... some of its notions and terms seem to anticipate the Wuzhen pian, a major neidan text written about fifty years later.
This passage demonstrates the doctrinal porosity between waidan and Neidan in Song-dynasty alchemical literature, showing how transitional texts anticipated major Neidan formulations.

The Fahui is firmly rooted in the main neidan textual legacy, quoting from nearly one hundred texts valued by this heritage.
This passage highlights Yu Yan's Fahui as a landmark Neidan commentary that systematically consolidated the tradition's textual canon through dense intertextual citation of the inherited heritage.
