Convergent in Appearance, Divergent in Spirit

Buddhism and Daoism may share the same words; each must return to its own Dao.

For over a millennium, the pervasive discourse of "Three Teachings Unity" and modern spiritual syncretism have propagated a seductive myth: that Buddhism and Daoism share the same ultimate origin and, by different paths, arrive at the same destination. Beneath a deceptively identical lexicon—mind, nature, light, spirit, emptiness, non-birth, and non-destruction—lies the deepest, most concealed philosophical fault line in East Asian intellectual history.

In Convergent in Appearance, Divergent in Spirit, this book executes a rigorous, multi-layered philosophical reconstruction comparing two foundational classics: the Mahāyāna Buddhist Shurangama Sutra and the Quanzhen Daoist internal-alchemy treatise Taiyi Jinhua Zongzhi (The Secret of the Golden Flower). Employing a sharp three-dimensional scrutiny of Ontology, Epistemology, and Soteriology, this masterwork dismantles a thousand years of semantic drift:

Ontology: The de-reified absolute subjectivity of Tathāgatagarbha (radical Emptiness) versus the reified cosmic substrate of Prenatal One Qi (Primordial Origin). Epistemology & Practice: Avalokiteśvara's passive, deconstructive "turning-back hearing" (the simultaneous extinction of subject and object) versus Patriarch Lü's active, intentional "returning the light" (energetic condensation and Kan-Li coition). Soteriology: The dissolutive ultimate of Nirvanic Quiescence (non-action, no-self) versus the generative superhumanization of the Pure-Yang Immortal (a body outside the body, self-mastered aggregation and dispersion).

Chuang also ventures into modern critical thought, laying bare Carl Jung’s "creative misreading" in psychologizing the Golden Elixir as the Self, while systematically dismantling contemporary pseudo-scientific analogies that crudely equate Buddhist/Daoist consciousness with the brain's Default Mode Network (DMN).

Brilliant, uncompromising, and deeply illuminating, this book is an indispensable guide for scholars of comparative philosophy, serious practitioners of meditation and internal alchemy, and any seeker navigating the confusing labyrinth of contemporary spirituality.
