Within the depth-psychology corpus, Buddha Nature (buddhata; tathāgatagarbha) functions as one of the most productive sites of convergence between Asian soteriological thought and Western psychological inquiry. The library's witnesses span classical Zen transmission, Tibetan tantra, comparative mythology, and explicitly therapeutic dialogue—yielding a spectrum of interpretations rather than a single settled position. Brazier reads Buddha Nature through the lens of humanistic psychology, equating it with Rogers's 'actualizing tendency' while insisting that its ethical dimension distinguishes it sharply from mere self-actualization. Spiegelman, working the Jung–Buddhism interface, recovers the tripartite Hua-yen formulation of Buddha Nature—as universal essence, driving force, and realized perfection—and maps it onto Jungian individuation and the Self. Suzuki locates the doctrine in the Mahayana axiom that all sentient and non-sentient beings are endowed with Buddha-mind and Buddha-body, making enlightenment a matter of recognition rather than acquisition. Evans-Wentz transmits the Zen formula most tersely: the difference between a Buddha and an ordinary person is solely one of recognition. Dōgen's Shōbōgenzō fascicle 'Buddha Nature' anchors the tradition's own canonical self-commentary, while Trungpa's index linking Buddha Nature to 'basic intelligence' and tathāgatagarbha sketches the Vajrayāna valence. The term thus marks a contested but generative intersection of ontology, psychology, and ethics in the corpus.
Trusting the buddha nature is similar to the humanistic idea that there is a reliable constructive growth process called the 'actualizing tendency'. This idea has been a powerful force in western psychology, too.
Brazier explicitly equates Buddha Nature (buddhata) with Rogers's actualizing tendency, positioning it as the therapeutic foundation of Zen therapy and grounding it within Western psychological discourse.

Chih-yen viewed the Buddha-nature as having a tripartite character: (1) the Buddha-nature itself, the genuine essence which is universally ever-present in all beings … (2) the Buddha-nature as the driving force … and (3) the Buddha-nature as perfectly realized through practice.
Spiegelman draws on Hua-yen Buddhism's tripartite model of Buddha Nature to articulate a structural homology with Jungian individuation, showing Buddha Nature as simultaneously ontological ground, psychological telos, and realized achievement.

Since buddha nature is our inseparable unity with the whole of existence, ethics are not seen as a restriction, but as a liberation. They are the way to realize our core nature and consequently are the path of truth and happiness.
Brazier argues that Buddha Nature reframes ethics from external constraint to intrinsic expression of one's deepest being, distinguishing the Zen therapeutic view from both psychoanalytic repression theory and humanistic ethics.

Hence the Mahayana doctrine that all beings, sentient or non-sentient, are endowed with the Buddha-nature, and that our minds are the Buddha-mind and our bodies are the Buddha-body.
Suzuki states the universal Mahayana axiom: Buddha Nature is not an aspiration but an ontological given, present in all beings without exception, rendering enlightenment a matter of recognition rather than attainment.

all things contain the Buddha nature from beginningless time … 'The only difference between a Buddha and an ordinary man is that the one realizeth that he is a Buddha and the other doth not.'
Evans-Wentz transmits the foundational Zen and Mahāyāna formula that Buddha Nature is timelessly universal, with the sole distinction between liberation and bondage lying in the act of recognition.

In this dialogue, Zhaozhou says just as the door of every house is connected to the 'capital' (eternal peace, Buddhahood, or nirvana), so too a dog definitely has Buddha-nature.
Dōgen's commentary on the Zhaozhou koan ('Does a dog have Buddha-nature?') affirms the universal presence of Buddha Nature through the image of every door opening onto the capital, making immanence the operative teaching.

we must awaken our innermost wisdom, pure and divine, called the Mind of Buddha, or Bodhi, or Prajna by Zen masters. It is the divine light, the inner heaven, the key to all moral treasures, the centre of thought and consciousness.
Jung cites a Zen adept's description of the awakened Buddha-mind as an inner divine light and moral centre, using it to illustrate how Oriental enlightenment experience approximates Western psychological categories of the Self and conscience.

The index entry confirms that Dōgen's Shōbōgenzō contains a dedicated fascicle titled 'Buddha Nature,' establishing it as a formal canonical locus within the classical Zen textual tradition represented in the corpus.

Buddha nature … See also intelligence, basic and tathagata-garbha
Trungpa's index cross-references Buddha Nature with 'basic intelligence' and tathāgatagarbha, locating the term within the Vajrayāna semantic field of intrinsic wakefulness rather than an extrinsic ideal to be achieved.

Every Buddha Thus Come [tathāgata] is one whose spiritual body is itself the inhabiting principle of nature [dharmadhātu-kāya]. Hence he may enter into the mind of any being.
Campbell's citation of the Amitayus meditation sutra frames the tathāgata's dharmadhātu-body as a principle immanent to all minds, implicitly grounding the cosmological vision in the universal accessibility that Buddha Nature doctrine asserts.

there is what the Lankavatara Sutra calls a 'turning about in the deepest seat of consciousness.' In this moment all sense of constraint drops away.
Watts describes the experiential correlate of Buddha Nature's awakening—the Laṅkāvatāra's 'turning about in the deepest seat of consciousness'—without naming the doctrine explicitly, pointing to the phenomenology that Buddha Nature doctrine explains.

All sentient beings without exception have the Buddha-nature … This very earth is the Lotus Land of Purity, And this body is the body of the Buddha.
Suzuki's verse citation equates immanent reality—earth and body—with the Buddha-realm, expressing the non-dual consequence of the Buddha Nature doctrine: that awakening reveals the sacred within the ordinary.
