Ignorance-Theory-Illumination: Four

This feeling of "I am ignorant" is a subjective experience that supports the existence of avidyā (ignorance) as a veiling power imposed upon Brahman. It represents a state wherein the soul remains ignorant of its true nature (Brahman), consequently creating the illusion that the world is real.

The Nyāya-Vaiśeṣika (Logical) Counter-argument and Advaitic Analysis:

The Nyāya-Vaiśeṣika philosophers, or logicians, vehemently oppose this claim. According to them, the experience "I am ignorant" does not prove the existence of avidyā, but merely indicates the absence of knowledge (Jñānābhāva). This feeling simply means that the individual lacks certain information or understanding, but it is not avidyā as some deeper metaphysical entity—that existence which is not merely part of the experiential world, but philosophically represents the fundamental reality of the soul or Brahman. This experience is merely a state of not possessing specific knowledge, which can be understood as 'absence' or 'non-existence.' For instance, when someone says, "I don't know the author of this book," it simply indicates the absence of that particular information, not any fundamental ignorance.

In Advaita Vedanta philosophy, avidyā or ignorance is a crucial concept that is not merely the absence of knowledge, but is considered a positive entity. When logicians interpret avidyā simply as the absence or non-existence (abhāva) of knowledge, Advaitins penetrate deeper and refute this view. Their argument is that if avidyā were merely the absence of knowledge, then it could be known through anupalabdhi (non-perception), like other absences. Anupalabdhi is an epistemological means that proves the absence or non-existence of objects. For example, when we do not see a pot in a room, we know the absence of the pot through non-perception.

But according to Advaitic doctrine, avidyā cannot be known through non-perception. The primary reason is that avidyā itself is the foundation of all proof and stands beyond being proven by any means of proof. Avidyā is that fundamental ignorance which veils the unity between Brahman and the individual soul and makes this world appear real. It functions as the fundamental basis of our cognitive processes, but is not itself subject to any proof. Avidyā is not graspable through perception or inference like an object, because it underlies all means of proof.

In Advaitic philosophy, the absence of knowledge is seen as a negative concept (abhāva-rūpa) that indicates the non-presence of something. For instance, when we say "there is no pot here," we indicate the absence of the pot; but avidyā is a positive entity (bhāva-rūpa). This means that avidyā is not merely emptiness or absence, but has its own real or active existence. It is an indescribable state between truth and falsehood, which is neither real nor unreal. It is a veiling power imposed upon Brahman.

Advaitins further argue that when saying "I don't know," we do not merely indicate the absence of knowledge. Rather, we indirectly point to the avidyā that underlies this absence. This "not knowing" is not merely a temporary or personal absence of knowledge, but signifies a deeper and more fundamental ignorance about the world and the nature of the self, which is created by avidyā. Avidyā itself is the primary obstacle on the path to liberation. Its destruction is possible only through self-knowledge, which realizes the unity of the soul with Brahman. Through this realization alone can one attain freedom from avidyā and all the bondage it creates.

Memory of Avidyā After Deep Sleep: "I knew nothing" (Na kiñcidavediṣam)—The Core Claim and Explanation of Advaitic Doctrine:

When a person awakening from deep sleep (Suṣupti) remembers—"I knew nothing" (Na kiñcidavediṣam) or "I was deluded" (Mūḍho'ham āsam)—Advaitins present this memory as powerful evidence of avidyā or ignorance. This memory after awakening from deep sleep proves that a state of ignorance existed during sleep. This memory does not merely witness the absence of knowledge, but indicates an awareness of a previous state of ignorance, something deeper than mere absence of knowledge. According to Advaitic doctrine, during deep sleep, though there is no external knowledge or worldly experience, a special kind of ignorance or avidyā remains active, which keeps the individual separated from this experience. In this state, witness-consciousness (Sākṣī-caitanya) remains active and directly perceives that ignorance. The feeling "I slept peacefully, I knew nothing" is not merely the absence of knowledge, but an experience of positive ignorance that enveloped deep sleep.

Nyāya-Vaiśeṣika Counter-argument and Advaitic Analysis:

According to Nyāya-Vaiśeṣika doctrine, this memory does not prove avidyā. In their view, the witness (Sākṣī) actually perceives the absence of knowledge during sleep. The witness remains present always—even during sleep—and then illuminates the absence of knowledge (Jñānābhāva). That is, witness-consciousness remains active then and directly perceives the absence of knowledge, but it does not perceive any independent, positive avidyā. Therefore, this is merely an indirect experience of the absence of knowledge, not direct proof of avidyā.

The Difference Between Logical Doctrine (Nyāya-Vaiśeṣika) and Advaita:

According to Nyāya-Vaiśeṣika doctrine, "memory" (parāmarśaḥ) is a special knowledge that leads toward inference (Anumāna). Their perspective does not align with Advaitic witness-theory. Advaitins argue that the witness perceives not merely the absence of knowledge, but a positive state of ignorance during deep sleep. According to them, if it were only the absence of knowledge, then after awakening from sleep, one would not have the feeling "I slept peacefully, I knew nothing." This feeling is a special positive experience that was covered by ignorance. For Advaita, the experience of deep sleep proves that a power, namely avidyā, remains active even in the absence of worldly knowledge and keeps that state veiled.

Inferring the Absence of Past Knowledge—The Core Claim and Explanation of Advaitic Doctrine:

Advaita Vedanta takes recourse to a formal inference to prove avidyā: "There was an absence of knowledge in me in the past" (Ahaṁ pūrva-kālīna jñānābhāvavān). This inference is an epistemological attempt to establish avidyā as an independent entity.

Past (Pūrva-kālīnaḥ): The context of this inference takes the time of deep sleep or suṣupti. During deep sleep, there is no external knowledge or mental process.

Sādhya (what is to be proved): The inference seeks to establish that there exists an absence of knowledge within the individual. This absence is not merely ignorance, but an active ignorance that makes the experience of deep sleep possible.

Hetu (reason): The absence of connection between the soul and mind, which connection is the cause of worldly knowledge. That is, during deep sleep there is no connection between soul and mind, and since this connection is the cause of worldly knowledge, the absence of worldly knowledge during this time is natural. But is this absence merely the non-presence of knowledge, or is it a positive ignorance? Advaitins support the second alternative. They argue that the absence of knowledge resulting from the lack of connection between soul and mind is actually a manifestation of avidyā, which keeps the state of deep sleep veiled. This avidyā is not a passive power, but an active veiling force.

Nyāya-Vaiśeṣika Counter-argument and Advaitic Analysis:

According to Nyāya-Vaiśeṣika doctrine, in deep sleep the soul-mind connection exists, but in a different form. They argue that if the soul-mind connection were completely absent, then the experience of sleep or memory of deep sleep would not be possible. According to them, it is because the soul-mind connection exists during deep sleep that memories like "I slept peacefully" are possible. This experience is itself a kind of avidyā, which according to them is the absence of knowledge. They claim that a special connection between soul and mind exists during deep sleep, which gives the experience of mental peace and absence of worldly knowledge.

On the other hand, Advaitic doctrine emphasizes—this is not merely the absence of knowledge, but a positive ignorance that makes the experience of deep sleep possible. Advaitins explain that though the connection between soul and mind is essential for worldly knowledge, in deep sleep a special kind of ignorance is present, which cannot be explained merely by the absence of connection. This ignorance (avidyā) operates during deep sleep, as a result of which worldly knowledge is not produced, but the individual's subjective peace is experienced.

Avidyā versus Absence of Knowledge: The Question of Proof

A central argument of Advaita Vedanta is that avidyā is not the absence of knowledge. Because it cannot be grasped by abhāva-pramāṇa (proof of absence). In Advaita Vedanta, avidyā is a positive entity (bhāva-rūpa). If it were merely the absence of knowledge (Jñānābhāva), then it could be grasped by "abhāva-pramāṇa" (such as non-perception). Abhāva-pramāṇa is a method of gaining knowledge that helps to know the absence or non-existence of an object.

Example: Śukti-rūpya (shell-silver) illusion—seeing a shell and mistaking it for silver. When a person mistakes śukti (shell) for silver and later realizes it is not silver, then he knows the absence of silver through non-perception. That is, the knowledge "there is no silver here" is confirmed not by direct perception or any other proof, but by non-perception. But avidyā cannot be known this way. Avidyā cannot be known by abhāva-pramāṇa, because it is not absence or non-presence, but a positive veiling power.

Definition of Avidyā (according to Advaitic doctrine): Avidyā is—"that which cannot be known by abhāva-pramāṇa" (abhāva-māna-agamyatvam). Avidyā is such an entity that cannot be grasped by abhāva-pramāṇa, nor can it be grasped by any other conventional proof (such as perception, inference, comparison, testimony). It is 'indescribable' (anirvacanīya). This means that avidyā can neither be called real nor unreal. It is a power imposed upon Brahman that makes the world appear real.

Logician versus Vedantin:

Logician: Logicians say that absence can be grasped through direct perception itself. We can directly see the absence of a pot. According to them, the knowledge "there is no pot here" comes through direct perception, because the empty space can be perceived.

Vedantin: Vedantins say that non-perception is a separate proof, but avidyā cannot be grasped even by non-perception. The reason for this is that avidyā itself is the fundamental basis of all proof and stands beyond being proven by proof. It is not an object of knowledge, but the fundamental veil of knowledge.

Removal by Knowledge and Refutation of Opposition:

Vedantin's argument: Avidyā is "removed by knowledge." That is, when true knowledge arises, avidyā disappears. Just as darkness is removed by light, similarly when Brahman-knowledge arises, avidyā is destroyed. This further strengthens the positive nature of avidyā. Avidyā itself is like darkness that is dissolved by light. Just as darkness is not the absence of light, but an entity opposite to light, similarly avidyā is not the absence of knowledge, but an entity opposite to knowledge, which is removed with the arising of knowledge. This concept highlights avidyā's role as a temporary entity, which is annihilated by knowledge of the ultimate truth, Brahman.
