Within the depth-psychology and perennial-philosophy corpus, ‘Manifestation’ designates the process by which an absolute, undifferentiated ground — variously named Brahman, the Absolute, the Infinite, Universal Mind, or libido — articulates itself into determinate form, whether as cosmos, psyche, or individual being. Aurobindo furnishes the most systematic treatment, arguing across The Life Divine and The Synthesis of Yoga that the universe is a ‘progressive self-expression’ of the Absolute, with Being and Becoming as its two irreducible terms; the Becoming is real by virtue of the Being that sustains it, and imperfection within manifestation is not an error but a structural necessity of a gradual evolutionary unfolding from the Inconscient toward Supramental consciousness. Campbell and Govinda approach the term from mythological and Vajrayana vantages respectively: Campbell identifies manifestation as the cosmic activity of a single ubiquitous power whose psychic correlate is libido, while Govinda maps graduated planes of manifestation through the trikaya doctrine. Jung treats manifestation obliquely but meaningfully, locating it in the dynamic tension of opposites — the spirit requires conflict to manifest at all. A key tension runs throughout: whether manifestation is ontologically real (Aurobindo’s realism), a half-real Maya (Advaita construals addressed and critiqued by Aurobindo), or purely phenomenal in the psycho-analytic register. The term thus bridges cosmological, soteriological, and psychological registers, making it a conceptual crossroads of the entire library.
