Yogacara

Asanga, Vasubandhu, Dignaga

Yogacara (Consciousness-Only) holds that all phenomena are transformations of consciousness (vijnapti-matra) with no external material world. Experience arises from the maturation of seeds (bija) stored in the alaya-vijnana (storehouse consciousness), which is shared across beings and perpetuates the appearance of an objective world.

I. Time

Extent Infinite
Ontological Status Emergent
Grain Discrete
Freedom Non-Deterministic
Traversability Cyclical
Dimensionality One
Direction Uni-directional

Time is emergent and infinite — it is a mental construction (vikalpa) projected by consciousness (vijñāna) rather than an independently existing reality. Time is continuous and cyclical: samsara extends without beginning through endless rounds of rebirth. It is uni-directional in ordinary experience but ultimately empty (śūnya) of inherent existence. In the transformation of consciousness (āśraya-parāvṛtti), the practitioner sees through the constructed nature of time.

II. Space

Extent Infinite
Ontological Status Emergent
Curvature Undefined
Dimensionality Three
Locality Non-local

Space is emergent and infinite — it is a representation (vijnapti) produced by the storehouse consciousness (ālaya-vijñāna) rather than an independently existing container. Curvature is undefined because space has no mind-independent geometric character. Space is non-local in the sense that spatial experience is internal to consciousness. The external world as spatially extended is "consciousness-only" (vijñaptimātra).

III. Matter

Extent Finite
Ontological Status Emergent
Conservation Non-conserved
Dimensionality Three
Locality Non-local

Matter is emergent and finite — it is a projection of consciousness, not an independently existing substance. The Yogacara motto "vijñaptimātra" (consciousness-only) means that what appears as external matter is actually a manifestation of the storehouse consciousness. Matter is non-conserved in the ultimate sense: it is empty (śūnya) of independent existence. It is non-local because material appearances arise within consciousness, not in an external spatial container.

IV. Observer

Time Instance Multiple
Space Instance Single
Extent of Knowledge Total
Retainment of Knowledge Total
Physicality Disembodied
Agency Active
Number Plural
Time Instance: Multiple — consciousness operates across multiple temporal modes: the alaya-vijnana (storehouse consciousness) carries seeds from past moments into the present, and the manas (self-grasping mind) projects into the future; the observer is not confined to a single instant but participates in the continuous stream of consciousness across lifetimes
Space Instance: Single — although consciousness is non-spatial in its ultimate nature, each individual consciousness stream (santana) manifests from a single perspectival locus; the appearance of spatial location is a construction of consciousness, but each being experiences it from one point
Extent of Knowledge: Total — the Buddha's consciousness achieves sarvajnata (omniscience) through the complete transformation of the alaya-vijnana into the Mirror-like Wisdom (adarsha-jnana); enlightened awareness knows all phenomena as they truly are — mere consciousness
Retainment of Knowledge: Total — the alaya-vijnana retains all experiential seeds (bija) without loss; nothing experienced is ever truly forgotten, as every impression persists as a seed capable of future maturation; in enlightenment, this retentive capacity is transformed into perfect wisdom
Physicality: Disembodied — there is no material body independent of consciousness; what appears as a body is vijnapti (representation) arising from the maturation of karmic seeds in the alaya-vijnana; the observer is fundamentally a stream of consciousness, not an embodied being
Agency: Active — consciousness actively constructs the entire phenomenal world through the maturation of seeds (bija) and the projective activity of manas; the observer is the agent of its own experiential reality, and liberation requires active meditative transformation (ashraya-paravrtti)
Consciousness: Present — consciousness is the sole reality in Yogacara; it is not merely present but is the very substance of all that exists; to be is to be a modification of consciousness
Number: Plural — individual consciousness streams (santana) are genuinely many, each carrying its own storehouse of karmic seeds; however, the shared alaya-vijnana establishes a common experiential world across beings, creating intersubjective coherence within irreducible plurality

V. Energy

Extent Infinite
Ontological Status Emergent
Conservation Non-conserved
Dispersibility Irreversible

Infinite and emergent — energy is a conceptual construction (prajnapti) arising within consciousness; it has no existence outside the transformations of the alaya-vijnana and is reducible to the maturation and exhaustion of karmic seeds. Conservation: Non-conserved — since all phenomena are impermanent (anitya) constructions of consciousness, energy can arise and cease without any conservation law; what appears as conservation is merely the regular patterning of seed-maturation. Dispersibility: Irreversible — the karmic process moves in one direction: seeds mature, produce effects, and are exhausted; only the radical transformation of enlightenment (ashraya-paravrtti) can halt this one-way process, but it does not reverse it.

VI. Information

Ontological Status Emergent
Conservation Non-conserved
Granularity Continuous

Information is mind-only (vijnapti-matra) — the external informational world is a construction of consciousness. There is no information 'out there' independent of the mind that projects it. Information is emergent from consciousness. It is non-conserved because the seeds (bija) in the storehouse consciousness (alaya-vijnana) ripen and exhaust themselves. It is continuous because the stream of consciousness is unbroken.
