Vasubandhu's Twenty Verses on Consciousness-Only

Vasubandhu's Twenty Verses on Consciousness-Only (Vimsatika-Karika)

1. Reality as Consciousness-Only

  • Yogacara Thesis: In Mahayana philosophy, reality is viewed as being consciousness-only.
    • Synonyms for Mind: The terms "mind" (citta), "thought" (manas), "consciousness" (chit), and "perception" (pratyaksa) are considered synonyms.
    • The word "mind" (citta) encompasses mental states and mental activities.
    • The word "only" specifically denies the existence of any external objects of consciousness.
    • Analogy: Mental representations might seem correlated with external non-mental objects, similar to individuals with vision disorders who "see" things that are not physically present (e.g., hairs, moons).

2. Objections to Consciousness-Only and Yogacara Replies

Objection 1: Irregularity and Functionality (Verse 1, 2)

  • If perception and consciousness occur without external objects, several issues arise:
    • Any idea could appear anytime, anywhere.
    • Different minds could contain ideas of different objects at the same time and place.
    • Objects could function unpredictably.
  • Specific Questions Posed:
    • If perception arises without an external object, why is it restricted to certain places and times?
    • Why does perception arise in the minds of all present, not just one, unlike optical illusions (e.g., hair, bees)?
    • Why do objects seen by those not afflicted perform functions (food, drink, etc.), while those seen in dreams or by the afflicted (e.g., dream food, illusory town) do not?
    • If external objects don't exist, these everyday experiences are inexplicable.

Yogacara Reply 1: Regularity within Consciousness (Verse 3a, 3b, 4a, 4b)

  • Dreams as Evidence (Verse 3a): Even within dreams, where external objects are absent, ideas arise in specific places and at specific times (e.g., bees, gardens, men, women).
  • Shared Experience in Hellish States (Verse 3b, 4b):
    • In hellish states, all condemned spirits (pretas) perceive the same phenomena (e.g., a river of pus and other hellish scenes like guardians, dogs, crows, moving mountains, torments).
    • This demonstrates that multiple minds can experience the same things without actually existing external objects.
    • These hellish experiences are psychological, not based on external objects.
  • Functionality in Dreams (Verse 4a): What is experienced in dreams can function as it does in the waking state.
    • Example: Nocturnal emissions of semen. A man dreaming of sexual intercourse may experience an orgasm and ejaculate, even without actual physical interaction.
  • Summary of Reply: These examples show that even without external objects:
    1. The mind can have specific ideas at specific times and places.
    2. Different minds can experience the same things.
    3. Experienced things can function in expected ways.

Objection to Hellish State Non-Existence

  • Why assert that things experienced in hellish states do not exist?

Yogacara Reply to Hellish State Objection

  • The hell-guardians, who inflict torment, do not themselves suffer the torments (e.g., standing on red-hot iron).
  • Dilemma: Are the guards sinners deserving punishment, or not?
    • If they are sinners, they should be suffering, not serving as tormentors.
    • If they are not, there's no reason for them to be in hell at all.
  • Conclusion: It is more logical to consider hell-guardians and other hellish experiences as mental images in the minds of the condemned.

Objection 2: Buddha's Teaching on Perception and Objects

  • The Buddha taught twelve foundations of knowledge (ayatanas): the six senses (seeing, hearing, smelling, tasting, touching, thinking) and their corresponding objects.
  • If consciousness arises through senses in response to external objects (as Buddha taught), how can reality be consciousness-only?

Yogacara Reply 2: Exoteric vs. Esoteric Teachings (Verse 8, 9, 10)

  • Teaching for Neophytes (Verse 8): The Buddha's teaching on the twelve ayatanas was an exoteric (publicly presented) teaching for new converts (neophytes).
  • Esoteric Meaning (Verse 9): This exoteric teaching has an esoteric (hidden or secret) meaning.
    • Both subjectivity (atman) and objectivity (dharma) arise from the unconscious (alaya-vijñana), which is the domain of 'seed-consciousness'.
    • The alaya-vijñana (storehouse consciousness) is the underlying consciousness from which all things arise, a reservoir of experiences and "seeds" for all mental constructions (perceptions, ideas).
    • Perception (e.g., vision) arises from a seed in the unconscious and results in an apparent object (e.g., color).
  • Gradual Initiation (Verse 10): The Buddha taught this way to gradually initiate disciples into the understanding of the insubstantiality of:
    • Self: No seer, hearer, smeller, taster, toucher, or thinker. All six levels of perception are merely representations of consciousness from the alaya-vijñana.
    • Objects: Objects of perception are also representations of consciousness-only, without inherent external objective existence.
  • Distinction between Constructed and True Reality:
    • We must distinguish between reality (self and objects) as constructed by ordinary consciousness (especially imagination) and reality in its "suchness" (tathata).
    • The constructed self (ego) and its subject-object duality are insubstantial, being transformations and representations of consciousness.
    • Beyond this, there is an ineffable (anabhilapya) transcendent Self, which is substantial (dravyatah) or "really real," known only by Buddhas and enlightened ones, and in which the subject-object duality does not arise.

3. Atomism and Experience

Objection 3: Existence of Atoms

  • How can we be sure the Buddha intended an esoteric meaning? Aren't there external, real atoms that, when aggregated, form perceived objects?
    • This refers to atomistic theories supported by schools like Vaisheshika (Hindu) and Vaibhashika (Buddhist).

Yogacara Reply 3: Problems with Atomism (Verse 11, 12, 13, 14a, 14b, 14c)

  • Atoms Cannot Be Proved (Verse 11): The existence of atoms cannot be proven because an object of perception is never:
    • A Unified Entity (Whole without parts): It's impossible to experience a whole independently of its parts; all perceived objects have, and are divisible into, parts.
    • Several Distinct Atoms: Individual atoms are imperceptible.
    • An Aggregation of Atoms: An aggregation of imperceptible components is itself imperceptible.
  • Logical Problems with Atomic Aggregation:
    • Six-sided Atom Contradiction (Verse 12): If one atom joins six others, the central atom must have six sides (six parts). But an atom, by definition, is indivisible and has no parts. This is a contradiction.
    • Shared Space Contradiction (Verse 12): If all seven atoms occupy the same location, they would effectively be a single atom, not an aggregation, another contradiction (two or more material entities cannot occupy the same space).
    • Impossible Aggregation (Verse 13): Some atomists argue that atoms cannot aggregate due to having no parts. Yet, they claim aggregations can form larger aggregations. If initial aggregation is impossible, subsequent aggregation is also impossible.
    • Atom with Parts (Verse 14a): If an atom has parts (e.g., a "front" or "back" to be in front of another atom), then it cannot be a unity (it is divisible) and thus not an atom, leading to a contradiction.
    • Overshadowing/Concealment (Verse 14b): If an atom has no parts (absolutely indivisible), it cannot have spatial extension or a location. Therefore, it cannot be lighted on one side and shadowed on another, as it has no sides. It's impossible for one atom to overshadow another.
      • Implication: If unextended atoms form the world, and they have no parts or location, then all atoms would be located in the same "no place" at the "no time," effectively implying the entire aggregation is a single, unextended atom.

Objection to Aggregations and Concealment

  • Why can't aggregations of atoms, rather than individual atoms, be subject to overshadowing and concealment?

Yogacara Reply to Aggregations Objection (Verse 14c)

  • This argument is only viable if aggregations are metaphysically different from the constituent atoms.
  • If there's no essential difference, then aggregations are no more subject to overshadowing or concealment than individual, partless, extensionless atoms.
  • Fundamental Point: Extensionless atoms cannot form aggregations extended in space, making them equally incapable of being illuminated or shadowed.

4. Monism and Experience

Question on Monism

  • What about the view that reality is an absolute and indivisible unity (metaphysical monism), contrasting with atomistic pluralism?

Yogacara Reply to Monism (Verse 15)

  • Monism is also refuted by actual experience:
    • No Gradual Motion: If reality were an absolute unity, there could be no gradual motion or arrival anywhere. One would simultaneously "be" everywhere.
    • No Perception/Non-Perception: It would be impossible to see only one side of an object while not seeing the other.
    • No Distinctions: There would be no differences between various beings (e.g., elephants, horses), as all would be one.
    • No Spatial Separation: All things would occupy the same place.
    • Visibility of the Subtle: Invisible things (e.g., minute aquatic bacteria) would be just as visible as macroscopic objects (e.g., mountains).
  • Conclusion: Both atomistic pluralism and metaphysical monism contradict human experience, which points to a world grounded in consciousness-only.

5. Dream States and Waking States

Objection 4: Distinction between Waking and Dreams

  • Waking objects are perceived as real, while dream objects are recognized as mentally constructed. This difference refutes consciousness-only.

Yogacara Reply 4: The Nature of Awakening (Verse 17b)

  • Dream Analogy: Someone who is not awake in a dream doesn't recognize the unreality of dream objects. Only after awakening does one "see through" them.
  • Waking Analogy: Similarly, only those who have achieved enlightenment are able to discern the unreality of the world presented in what is commonly considered the "waking state."
  • Conclusion: Both dream and so-called waking experiences are similar in conceptual nature, being superseded by a "higher consciousness" in enlightenment.

Objection 5: Moral Consequences

  • If there's no essential difference between dream and waking states in terms of extra-mental objects, why are we morally concerned about waking actions but not dream actions?

Yogacara Reply 5: Control of Mind (Verse 18b)

  • In the dream state, the mind is dulled by sleep, resulting in little control over actions and their consequences.
  • In the waking state, the mind generally has greater control over what happens.
  • Conclusion: The consequences of waking actions hold greater moral seriousness due to this difference in mental control.

6. Interactions Between Individuals

Objection 6: Mutual Influence of Minds

  • If perception arises from within one's own stream of consciousness (not external objects), how can one mind be influenced by another (e.g., by friends, teachings)?
  • If no external objects, friends and teachings cannot exist outside one's consciousness.

Yogacara Reply 6: Interactive Streams of Consciousness (Verse 18a)

  • The streams of consciousness in different minds do mutually influence each other.
  • This interaction of minds demonstrates interconnectedness but does not prove the existence of external material objects.

Objection to Killing

  • If reality is consciousness-only, bodies don't exist. How, then, can butchers kill sheep (if neither have bodies)? How can butchers be blamed for taking life?

Yogacara Reply to Killing (Verse 19)

  • Definition of Killing: Killing is the disruption of one stream of consciousness by another stream of consciousness.
  • Evidence of Mental Power: Scriptural texts attest to the mental power of one mind to affect another (e.g., loss of memory, demon possession, mental telepathy, inducing dreams).
  • Mechanism of Killing: To kill is to fatally alter another's life force, causing it to flow in a different direction.

7. The Problem of Other Minds

Objection 7: Knowledge of Other Minds

  • If reality is consciousness-only, how can one mind know other minds? Doesn't knowledge of other minds refute the consciousness-only thesis?

Yogacara Reply 7: Enlightened Knowledge (Verse 21)

  • The Unenlightened: Those who are unenlightened are bound by ignorance and subject-object thinking. They cannot know the true minds of others, nor the true nature of their own minds.
    • At the level of ordinary consciousness, the existence of other minds is inferred by analogy to one's own mind, but this is not knowledge of the True Mind or True Self.
  • The Enlightened: Those who are enlightened are liberated from ignorance and have transcended subject-object consciousness.
    • They know their own true minds and the true minds of others.
    • They have achieved true Selfhood.
  • Conclusion: What is known to the enlightened is unknown to the unenlightened.

8. Conclusion (Verse 22)

  • The doctrine of consciousness-only is infinitely deep and subtle, offering limitless wisdom.
  • Vasubandhu states that he wrote the treatise to the best of his ability but cannot fathom all its complexities.
  • The doctrine can be grasped in its entirety only by the enlightened ones.
  • Its fullness transcends logic and even Vasubandhu's comprehension.
  • Enlightened ones know it fully because they have overcome all obstacles to true knowledge.
