The Lamp of Ignorance-Theory: Two

Doubt (Saṁśayaṁ): This is a state of uncertainty where one is unable to determine truth. It is an oscillation between two or more contradictory alternatives, where no definitive conclusion can be reached.

Misapprehension (Viparyayaṁ): This is an erroneous perception of reality, where falsehood is believed to be truth. It is delusion or false knowledge, such as mistaking a rope for a snake.

Other Internal Qualities (Guṇāntaraṁ): Other internal qualities that may oppose or contradict true knowledge, such as negligence or indolence, which obstruct the attainment of correct knowledge.

These are certainly contrary to knowledge, and the Siddhāntin argues that "indescribability (Anirvacanīyatvam) is not appropriate for them." For instance, doubt and misapprehension are defined psychological states or cognitive processes. They can be described, analyzed, and understood within the framework of knowledge. It is psychologically possible to explain why a person suffers from doubt or why misapprehension occurs. They have a beginning and an end, and they can be removed through knowledge.

Moreover, if indescribability were imposed upon these contraries of knowledge, then "their positive existence (Bhāvarūpatvaṁ) would be compromised or undermined." Doubt and misapprehension are not mere absences; they are positive mental states or processes. They possess a definite nature and can be experienced. A person experiences doubt or misapprehension, and these have a real presence in their psychological world. Since they are "positive entities," that is, possessing affirmative existence, they cannot be identified as avidyā.

In the Advaitic tradition, avidyā is understood as a singular, beginningless, and indescribable power that veils the true nature of the Self. Avidyā is not merely a mental state that can be easily removed by knowledge; it is such a fundamental force that creates the entire world of māyā. For the Siddhāntin (the Advaitin), avidyā is a concept that cannot be clearly defined. It is called "indescribable"—meaning neither absolutely real (sat) nor absolutely unreal (asat). Viewed in the light of Brahman-knowledge: avidyā has no ultimate existence. Brahman alone is real; therefore avidyā is actually non-existent. That is, from the absolute standpoint, avidyā is not a real entity. But in everyday experience (at the vyāvahārika level) we see the effects of avidyā. Here avidyā functions as a positive power—it conceals truth (veiling power, āvaraṇa-śakti); it makes the world appear through illusion or māyā (projecting power, vikṣepa-śakti). Though avidyā is non-existent in ultimate truth, in practical experience it is an effective power. Just as a dream does not actually exist, but functions like reality within sleep. Similarly, avidyā is false from the ultimate perspective, but in the experiential world it becomes effective by creating the world through māyā. Avidyā does not exist in absolute truth, but because it exists at the level of experience, we see and enjoy the world.

Therefore, to equate avidyā merely with the defined contraries of knowledge would conflict with its fundamental indescribable character. Avidyā is not a temporary or individual mental state, but rather a beginningless and universal entity that remains until the liberation of the individual. This deeper and more fundamental nature is what distinguishes avidyā from mere absence or contrary knowledge.

Everything other than Knowledge (Vidyā) ultimately resolves into the state of avidyā (ignorance)—this profound claim establishes the foundation for a fundamental philosophical inquiry into the nature of reality and understanding. In Indian philosophy, particularly in Advaita Vedanta, avidyā is not merely the absence of information, but rather a fundamental misunderstanding that gives birth to erroneous conceptions about our true being and the nature of the world. At the center of this inquiry lies a core principle: avidyā has no definition or proof. This claim is challenged by opponents through various proposed definitions, which are systematically examined and refuted to further consolidate the original position. This philosophical journey not only grasps the nature of avidyā, but also unveils the subtle distinctions between knowledge and existence.

To understand the nature of avidyā, various definitions proposed by different philosophical schools have been examined one by one, exposing their weaknesses. This process of refutation helps clarify the true essence of avidyā.

1. That which is overcome by knowledge is ignorance (Jñāna-nivartya ajñānam):

This apparently simple definition claims that ignorance is merely that which is defeated or cancelled by knowledge. This definition may seem consistent with everyday experience, where the acquisition of new knowledge removes previous misconceptions. For example, mistaking a rope for a snake in a dark room (the rope-snake illusion) is immediately dispelled when the rope can be seen by light. This example proves that knowledge is the antidote to ignorance.

However, this definition is not suitable for avidyā, as it creates a fundamental logical error known as "over-extension." The main reason for this is: prior knowledge (pūrva-jñāna) is itself overcome by subsequent knowledge (uttara-jñāna). For instance, when we gain preliminary understanding of a subject and later acquire deeper knowledge, the preliminary conception is corrected or cancelled by the new knowledge. The ancient notion that 'the earth is flat' was once considered knowledge, but later the concept of a spherical earth cancelled that prior knowledge. If this definition is accepted, then prior knowledge, since it is subject to negation, would also have to be considered a form of avidyā.

This creates a circular problem that obscures the distinction between different levels of knowledge and true ignorance. The implication is: if whatever is overcome by knowledge is avidyā, then knowledge itself, in its previous form, falls within the scope of ignorance—which is a self-contradictory outcome for a system aimed at separately defining avidyā from vidyā. This definition questions the very process of knowledge and fails to define avidyā in a way that brings out its distinctive characteristics. If avidyā is defined merely through being overcome by knowledge, then it ignores its fundamental and beginningless being.

2. That which, while being a beginningless positive entity, is overcome by knowledge, is ignorance (Anādi-bhāvatve sati jñāna-nivartya ajñānam)

To remove the limitations of the previous definition, a more subtle proposition has been brought forward: avidyā is not only overcome by knowledge, but it is also a "beginningless positive entity." This qualification aims to distinguish avidyā from temporary or transient errors. It seeks to convey that avidyā is not an accidental mistake or misconception, but rather a fundamental and timeless positive entity that is the root cause of world-creation. In Indian philosophy, "bhāvarūpa" means an existent, positive, and qualified entity, not merely absence or non-presence. The word 'anādi' indicates its originlessness, meaning avidyā has no beginning. However, upon close examination, this definition also does not stand.

Avidyā is—a beginningless (anādi), positive entity that is removed by knowledge; this means—avidyā is not just error or temporary, but it is beginningless (anādi), yet when true knowledge comes, it dissolves. "Over-extension" (ativyāpti) fault is: when any definition becomes so broad that it begins to capture other, irrelevant things besides the actual subject—then it is called over-extension. For example, the Self (Ātman) is also beginningless (without beginning) and a positive entity (the very form of consciousness). If it is merely said—"avidyā is beginningless, positive, and removed by knowledge"—then the Self would also be pulled into this.

Though the Self is beginningless, it is never overcome by knowledge. The Self is indeed the very form of eternal knowledge. Yet if the definition is not properly limited, then the Self would be wrongly placed in the category of avidyā—as if the Self could also be removed by knowledge. This is philosophically erroneous (doṣa). Suppose someone said, "śaśakśṛṅga (rabbit's horn) means something that was never born (beginningless)."—this definition would capture not only rabbit's horn, but many other things that were never born. This is over-extension.

The Self is absolute truth, indestructible and beginningless, which cannot be overcome by any knowledge. The over-extension of avidyā is an important philosophical problem, because the Self is often considered above such obstacles. The Self is of the nature of supreme knowledge and cannot be influenced or negated by any worldly knowledge. The Self is eternal and immutable, so if it were overcome by knowledge, its eternal nature would be compromised. Therefore, the definition causes over-extension in its scope, wrongly including entities that should not come under its purview.

Besides, an ancient view (Prācīna-mata) raises a fundamental challenge: how can a beginningless positive entity (Anādi-bhāva-rūpaṁ), such as ignorance, be overcome? If something has no beginning, how can it have an end through the acquisition of knowledge? As an analogy, blackness (Śyāmatvaṁ) in atoms is given, which is considered to be overcome by God's knowledge. In some philosophical systems, the inherent qualities of atoms, such as their color, are considered beginningless. Although God's (Īśvara) omniscient knowledge can understand or influence these qualities, they are not overcome in the way that misconceptions are overcome by human knowledge. And if obstruction (Nivarttyatvam) is claimed for beginningless positive entities, then it creates problems similar to over-extension.

The matter of "blackness in atoms" (Śyāmatvaṁ in atoms) mainly comes from Nyāya-Vaiśeṣika philosophy. They believed that all substances in the world are composed of four types of fundamental atoms: earth, water, fire (tejas), air. Each atom has its own inherent qualities (svābhāvika guṇa), which are eternal and beginningless. "Kṛṣṇatva" means black color or blackness, that is, where there is no presence of color. Some ācāryas said that the inherent color of certain specific atoms is black. This color was not born (there is no color there), meaning it is beginningless. It is not an error, but the natural characteristic of the atom.

According to Nyāya-Vaiśeṣika, God is omniscient, so God knows this blackness of atoms. But this knowing is not like removing misconceptions (as human avidyā is removed by knowledge), because blackness is not an illusion—it actually exists, as an inherent quality of atoms. The blackness of atoms was not established through removing any existing delusion. The Advaitins said: if avidyā is called a "beginningless positive entity," then it would become eternal like the blackness of atoms. But avidyā cannot be eternal—because when Brahman-knowledge comes, avidyā is removed. Therefore it would be wrong to place avidyā in the same category as blackness.
