Buddhism vs Spira’s Non-Duality
Buddhism’s Empty, Illusory Phenomenal Consciousness and Spira’s Non-Duality, compared field by field from their entries in the Atlas.
At a glance
- Both belong to the Idealism family in Kuhn's Landscape of Consciousness.
- They give the same kind of answer on life after death, mind uploading and meaning and purpose.
- On AI consciousness, Buddhism says “Uncertain” and Spira’s Non-Duality says “No”.

The claim
In brief
BuddhismThis theory suggests that the sense of phenomenal consciousness or 'what-it-is-like-ness' is an instance of cognitive illusion, rejecting the existence of a permanent, inner 'self' or 'soul'. It posits that consciousness, like all phenomena, is ultimately empty of intrinsic nature, and is better understood as a network of relational processes.
Spira’s Non-DualityThis theory proposes that ultimate reality is a single, infinite, and indivisible pure consciousness (non-duality), from which all objects and individual selves derive their apparently independent existence. It asserts that our essential nature, which is this pure consciousness, transcends the limits and destiny of the physical body and mind.
What consciousness is
BuddhismConsciousness (in the phenomenal sense) is identified as a cognitive illusion or conventional reality constituted by a network of processes/relations (Madhyamaka) or as an inner subjective substrate of representations (Yogācāra).
Spira’s Non-DualityConsciousness is identified as the single, infinite, and indivisible reality (pure consciousness) from which all apparent objects and individual selves derive their existence.
Big questions
Can AI be conscious?Differ
BuddhismUncertainIf consciousness is fundamentally an illusion arising from a network of processes, it is unclear whether advanced computation (AI) can replicate the complex conventional reality or the specific non-self processes that generate this illusion, even though computation is not fundamentally ruled out.
Spira’s Non-DualityNoIf consciousness is the singular, non-material ultimate reality, artificial systems (being derived/material objects) cannot achieve true consciousness, only a functional imitation or borrowing of existence from the ultimate reality.
Does consciousness survive death?Both agree
BuddhismYesThe eighth (store-house) consciousness persists after death, carrying karmic energy through cycles of reincarnation. However, survival often entails expansion back into cosmic consciousness, blurring or banishing individual first-person identity ('being sugar').
Spira’s Non-DualityYesThe theory explicitly states that our essential nature, being pure consciousness, does not share the limits or destiny of the body and mind, implying survival or continuity beyond biological dissolution.
Could a mind be uploaded?Both agree
BuddhismNot neededThe theory already provides a mechanism for persistence (the eighth consciousness) or transcendence (ninth consciousness), making artificial, digital duplication (virtual immortality) philosophically moot.
Spira’s Non-DualityNot neededSince the essential self is fundamentally non-physical, infinite consciousness, digital duplication of the body/mind is unnecessary for the persistence of the essential self.
Does it give life meaning?Both agree
BuddhismCosmic/UltimateThe ultimate goal is spiritual attainment (reaching the ninth consciousness or Buddha nature), which serves as the core source of energy and ultimate fulfillment, moving beyond merely humanistic purpose.
Spira’s Non-DualityCosmic/UltimateConsciousness is the foundation of reality ('the nature of reality') and understanding this non-dual essence is the key to achieving ultimate peace and happiness, providing inherent cosmic purpose.
Nature of mind
Ontology
BuddhismIdealism (specifically the Yogācāra school) or Deflationary Relationalism (specifically the Madhyamaka school), where all things are conventionally real but ultimately empty of intrinsic nature.
Spira’s Non-DualityOntological Idealism. The theory posits consciousness as the ultimate, singular, fundamental existent.
Mind and body
BuddhismThe relationship is understood as interdependent and relational, lacking intrinsic self/substance. The illusion of a centralized mind or self is rejected.
Spira’s Non-DualityThe essential nature of the self (consciousness) is held to be independent of the physical body and mind. Physical existence, and all experience, is mediated through the mind, which is derived from the fundamental consciousness.
Fundamental or emergent
BuddhismConventional reality constituted by relations. It is neither a primitive substance nor an emergent property in the typical Western sense, as the phenomenal self it describes is fundamentally illusory.
Spira’s Non-DualityPrimitive/Fundamental
Qualia
BuddhismQualia ('what-it-is-like-ness') are rejected as real, intrinsic properties and are instead viewed as illusory, dissolving away in favor of a network of underlying processes.
Spira’s Non-DualityQualia (multiplicity and diversity of experience) are seen as manifestations or derivations of the underlying singular pure consciousness, borrowing their apparent independent existence from it.
How it works
Mechanism
BuddhismThe principle of emptiness (lack of intrinsic nature) applied to all phenomena, resulting in the realization that phenomenal consciousness is a cognitive illusion.
Spira’s Non-DualityNon-Duality, defined by the ultimate identity between the essence of the self and the ultimate reality (pure consciousness).
Where it is
BuddhismNon-localized. Consciousness is often understood relationally. The ninth consciousness (Buddha nature) is the fundamental, purest core.
Spira’s Non-DualityUbiquitous/Cosmic. Consciousness is the underlying reality (single, infinite, indivisible) that pervades and underpins all existence.
What it does
BuddhismThe inward-directed seventh consciousness causes the concept of self, which is the source of deception. The eighth consciousness stores karmic energy and persists across death, thus enabling rebirth.
Spira’s Non-DualityConsciousness functions as the ontological source of all existence. Achieving the recognition of this pure consciousness is tied to the ultimate goal of finding lasting peace and happiness.
Evidence and criticism
Testability
BuddhismLargely conceptual, based on internal philosophical coherence and phenomenological insights gained via meditative practices. Empirical studies sometimes correlate high-level meditation states (nirodha-samāpatti) with measurable brain changes (reduced synchronization).
Spira’s Non-DualitySpeculative/Conceptual. The theory relies on philosophical and spiritual recognition of ultimate reality rather than empirical methods based on third-person observation.
Tests so far
BuddhismStudy of high meditative states (nirodha-samāpatti) showing reduced overall brain synchronization.
Spira’s Non-DualityNot stated
Criticisms
BuddhismWestern philosophers often find the core claim—that phenomenal consciousness is illusory—counter-intuitive and untenable. Internally, tension exists between the idealistic Yogācāra school and the relational Madhyamaka school.
Spira’s Non-DualityLike other Idealist theories, it faces the challenge of explaining precisely how the fundamental, non-material consciousness generates or interacts with the apparent physical world and matter.
