So then the qualities (dharma) of worldly objects—signified by "you" (yusmat)—are superimposed upon the Self, just as we take upon ourselves the honor or shame of our children. And what is meant by "I" (asmat) is that internal instrument (antahkaraṇa), that faculty of inner experience which is conscious in nature—distinct from the inert world. It is not pure consciousness itself, but rather through this internal instrument a false attribution (adhyāsa) occurs upon the Self. Thus the body's qualities—"I am thin, I am fat"—are imposed upon the Self.
Here the word 'dharma' (quality) is used to show that bodily attributes (such as being human, being thin or fat) are superimposed upon the Self—yet we do not say directly "I am the body." And it is precisely on the basis of this superimposition of qualities (dharma-adhyāsa) that the scriptures have prescribed various rules of action. This superimposition is no mere metaphor; it is a literal fact. We truly mistake the Self, confusing it with the body or the body's qualities. And the entire edifice of scriptural injunctions rests upon this fundamental error.
Superimposition (adhyāsa) is not a rhetorical game, but a literal false attribution. We fuse children, wealth, body, and bodily qualities into our sense of self. This very misattribution is the root of bondage. The rules and ordinances the scriptures prescribe are themselves grounded in this false notion—because we identify ourselves with body, mind, and possessions. Thus the commentator says: "I am healthy or sick"—such statements truly amount to imposing the body's qualities upon the Self. This is the true nature of superimposition.
What then is meant by 'reasoning' (tarka)? It signifies the application of logic, or reasoning itself. Yet this is merely a synonym. Its true character is explained thus: reasoning is a kind of reflective inquiry through which the possibility or impossibility of the means (pramāṇa), the capacity (śakti), and the subject matter (viṣaya—namely, the identity of Brahman and the individual Self)—these are determined.
The objector (pūrvapakṣī): If that is so, then Vedānta must depend upon reasoning to prove the validity of its own claims. In that case it ceases to be an independent means of knowledge, and thus becomes invalid.
The respondent (siddhāntī): This is not so. Vedānta does not become invalid. For the knowledge that Vedānta imparts through its own inherent power (sva-śakti) is free from doubt, infallible, and reveals its specific subject matter. That subject is the identity of the Self and Brahman.
The objector: Then what is the use of reasoning? If the great statement (mahāvākya) itself is capable of giving knowledge of the identity of the individual and Brahman, what function does reasoning serve?
The respondent: The function of reasoning is to remove obstacles. When the subject matter—the unity of individual and Brahman—appears impossible, the fruits of this knowledge (namely, the cessation of life's suffering and calamity) do not manifest. Then reasoning proves its possibility (sambhāva) and thus removes those obstacles.
An example: In the mahāvākya "Tat Tvam Asi" (Thou Art That), the word "Tat" signifies Brahman, and "Tvam" signifies the individual. But the individual thinks—"I have nothing in common with Brahman; indeed, I am of an entirely opposite nature." Because of this false notion, even when knowledge arises from the mahāvākya, the individual cannot hold fast to the truth. But when reasoning first demonstrates to him the possibility of his own identity with Brahman, then he can acknowledge and grasp that knowledge.
To put it simply—Vedānta itself is the means of knowledge; it possesses the capacity to impart wisdom directly. Reasoning does not directly produce knowledge; rather, it removes the mental obstacle that declares something "impossible." Thus the meaning of the scriptural statement (such as "Tat Tvam Asi") becomes fixed in the seeker's mind, and truth shines forth clearly.
Vedānta (scripture) itself is the means of knowledge (pramāṇa). It directly gives knowledge of the Self and Brahman. Yet within us stand many obstacles—doubts, seeming impossibilities, objections.
Argumentation (or logic) performs the work of removing that obstacle.
Example 1: Imagine a doctor prescribes medicine for you. The medicine itself is the true cure, the medicine that heals the disease. But you—the patient—are afraid: “Won’t this medicine have side effects? Is it really right for my body?” Then the doctor explains why it is safe, how it works. Here, the doctor’s argument (reasoning) does not cure the disease; it only removes fear, preparing your mind to receive the medicine without doubt. But the medicine (the scripture) cures the disease.
Example 2: Suppose in a dark room you have mistaken a rope for a snake. The scriptural utterance (Vedanta) says: “It is a rope, not a snake.” But doubt still arises in your mind: “No, the snake is moving—how could a rope do that?” Then the teacher or guru uses reasoning to explain: “A rope, whether in light or darkness, looks the same—cast off your habitual impressions of a snake and look toward the rope; then you will understand everything. And if it were truly a snake, there would be a hood, markings, hissing sounds; where are these?” This reasoning breaks your false understanding—thus the scripture itself reveals the truth.
Example 3: The great utterance of scripture—”Tat Tvam Asi” (You are That, Brahman). The individual soul thinks: “I am small, weak, limited. Brahman is infinite. How can these two ever be one?” This doubt itself is the obstacle. Logic here says: “You are not truly the body, mind, or senses—these are ever-changing. But the conscious being that witnesses them, that is your true self. And that very consciousness-principle is Brahman.” Thus logic removes the obstacle, and the scripture’s word becomes knowledge.
Vedanta = the true light. Logic = the clearing away of clouds. The light has always been there, but the clouds prevented it from being seen. The fundamental meaning of logic (tarka)—reasoning (Reasoning), discernment (Rational inquiry), discrimination (Discrimination), the testing of proof (Testing validity). In philosophy, logic means a rational process of discernment through which we may understand whether a piece of evidence is truly valid, whether a principle (the law of causation) is operating, and whether something (the identity of Brahman and self) is possible.
Logic’s work is to dispel doubt—such as, “Can I truly be Brahman?”—removing the sense of impossibility. Logic is the aid in understanding scripture—scripture alone reveals truth, but logic clears away obstacles. The refutation of error—using logic to break down the arguments or objections of opposing views. Reason (Reason), investigation (Investigation), debate (Debate), dialectical inquiry (Dialectic inquiry), the search for certainty (Enquiry for certainty)—all these are employed to convey what logic means.
Scripture says: “You are Brahman.” But the individual soul thinks: “I am limited.” Then logic explains: “What is limited is the body-mind, but you are its witness. The witness is not limited. Therefore you are the infinite Brahman.” Thus logic is like clearing the branches of a tree so that the sunlight of scripture (the scriptural word) can fall directly upon it.
The goal of Nyaya (logic) = the attainment of correct knowledge (proof)—logic is the means to assist it. Logic means examining the possibility or impossibility of something. If someone says, “There is fire, because smoke is visible,” then logic asks: “But what if something like mist appears, looking like smoke?” In this way, by examining possibility and impossibility, one arrives at the correct conclusion—this is logic’s work. Logic here tests the validity of reasoning.
The goal of Vedanta = knowledge of non-dual Brahman. Here scripture is the primary evidence. Logic here is scripture’s aid. Scripture says: “Tat Tvam Asi”—you are Brahman. But the soul thinks: “I am limited, Brahman is infinite. How can identity be possible?” Here logic comes to help—limitation belongs to body-mind, not to the self. The self is ever infinite and consciousness. Therefore identity is possible. Logic clarifies the scriptural utterance to make non-duality intelligible.
In Nyaya: logic is the means of testing evidence. In Vedanta: logic is the means of illuminating the truth of the scripture’s utterance.
An example concerning Nyaya-philosophy: Someone says—”The tree is on fire, because we see smoke.” An objection arises: “It could be mist rather than smoke.” An example concerning Vedanta: The scripture declares—”I am Brahman.” Logic objects: “But I experience suffering and pain! How can I be Brahman?” The answer comes: “Suffering and pain belong to the body and mind, not to the Self.” Thus in Nyaya-philosophy, logic is a test of proof, while in Vedanta, logic is an auxiliary that illuminates the meaning of scripture.
