Śaṅkarācārya introduces the concept of "adhyāsa" (superimposition) at the very outset of his commentary on the Brahma Sutras, because the root of all human suffering and affliction lies in false knowledge—in mistaken identification. We mistake the body, mind, and senses for the self. From this delusion spring forth the notions of birth and death, pleasure and pain, bondage and liberation.
Adhyāsa is the imposition of one thing's attributes upon another—like mistaking a rope for a serpent in the darkness. Like seeing the reflection of a red flower in a crystal and imagining the crystal itself is red. In exactly this way, adhyāsa is the superimposition of the qualities of body, senses, mind, and ego upon the self.
Let us understand the principle of "yuṣmad-asmat"—the distinction between the second person and the first person. Śaṅkarācārya teaches: "You" (yusmad) = the external world, the body, the senses, the not-self. "I" (asmat) = the inner self, consciousness, the eternal witness. These are utterly opposed. The not-self is insentient and ever-changing. The self is consciousness itself, unchanging. Yet mankind confuses the two—"I am the body," "my child," "my wealth"—this very confusion is adhyāsa.
Why is it called unreal (mithyā)? Adhyāsa is neither wholly true nor wholly false. Consider the dream—upon waking, we know it was false, yet while dreaming it seemed absolutely real. Precisely so: the superimposition of body and mind upon the self seems real even in the waking state, but once knowledge dawns, it stands revealed as false.
The relationship between ignorance (avidyā) and superimposition: Avidyā is not knowing the true nature of the self. Adhyāsa is the manifestation of that ignorance—it falsely overlays body and mind upon the self. As when we mistake the rope for a serpent through failure to perceive the rope rightly. Avidyā is the cause; adhyāsa is its effect.
Why is adhyāsa without beginning (anādi)? Because from birth itself, man thinks—"I am the body," "I am the experiencer," "these are mine." This error has no discernible point of origin. Hence it is called anādi (beginningless). Yet it remains unreal (mithyā), for it shatters the moment knowledge arises.
The varieties of superimposition: dharmādhyāsa (superimposition of attributes)—such as "I am gross," "I am fat," "I am ill"—attributing bodily qualities to the self. And arthādhyāsa (superimposition of substance)—such as "I am the body," "I am the mind"—directly identifying body or mind as the self.
Why is knowledge alone the means to liberation? Action (sacrifice, ritual) produces something new, but liberation is not a new creation. Liberation means the removal of superimposition. As when clouds disperse, the sun becomes visible—not born anew, but revealed. Similarly, when knowledge arises, the self stands unveiled, and liberation is accomplished.
The fundamental teaching of the superimposition commentary: Man's bondage springs from false knowledge (adhyāsa). Its root is ignorance (avidyā). Its manifestation is the thought "I am the body," "this is mine." The purpose of scripture is to shatter this superimposition. The means is knowledge of the non-duality of self and Brahman. The fruit is liberation—a state where birth and death, pleasure and pain, bondage and liberation are not even conceived. Thus the superimposition commentary establishes the foundation of Advaita Vedānta.
The purpose of beginning Vedantic study is this: to dispel mistaken notions. For all suffering springs from false knowledge (ignorance). When that false knowledge is removed, there arises knowledge of the non-dual unity of the individual self with the supreme self. Hence it is said: "to remove this cause of suffering"—here the fruit or necessity (prayojana) is indicated. "To gain knowledge of the unity of self and supreme self"—here the subject matter (viṣaya) is indicated.
A question arises—what then is the purpose of that commentary which begins with "yuṣmad-asmat" and concludes with "sarvalokapratiksaḥ"? The answer is: that commentary's task is to demonstrate that all of man's thought and conduct actually arise from false knowledge. Within them lies the mark of ego.
By example—"ahaṃ manuṣyaḥ" (I am a man). Here the self is identified with body or senses. "Ahamdam" (I am this). "Mamedam" (This is mine—child, wealth, possessions). When man thinks "I am the body" or "I am the senses" or "these are mine," he falls into the delusion of ego.
# Vedanta Begins by Breaking False Notions
Vedanta begins by shattering false notions (ego), and revealing this truth: the Self is not the body-mind, but is identical with Brahman itself.
The introduction (upakramaṇikā) to Adi Shankara’s commentary on the Brahma-sutra—beginning with “you-and-I” and ending with “all worlds are directly perceived”—is the gateway to understanding Vedantic philosophy. The Brahma-sutra-bhāṣya is the principal exposition of Vedanta doctrine, the foundational text of Shankara’s Advaita Vedanta. Before the main text, Shankara offers a preamble called the Adhyāsa Bhāṣya (Commentary on Superimposition). There he explains adhyāsa—the mechanism by which we project onto the Self what is not the Self, and confuse the Self with body, mind, and senses. This crucial passage opens with “the notion of you-and-I” and closes with “all worlds are directly perceived.”
In the Adhyāsa Bhāṣya, Shankara states at the outset: the root of all human suffering lies in superimposition born of ignorance. We mistakenly say—”I am a man,” “I am the body,” “This is my child, my wealth”—yet in truth, the Self is not identical with any of these. The Self is eternally free, the very form of Brahman.
We live our daily lives under a profound delusion. This delusion is called *adhyāsa* (superimposition): the confusion of *ātman* (consciousness, the immortal, the pure, the immutable) with *anātman* (the body, the senses, the mind, pleasure and pain). When I say “I am a man,” I am superimposing the body upon the Self. When I say “I am happy or suffering,” I am attributing to the Self qualities that belong only to body and mind. When I say “This is my son, my money,” I am extending the sense of “I” to things external, projecting the Self outward. All of this is adhyāsa.
From this superimposition springs *ahaṃkāra*—ego, the sense of “I am the doer”—and *mamakāra*—the possessive sense of “mine.” And from these arise sorrow, fear, attachment, desire. Therefore, superimposition is the root cause of suffering. Before the Brahma-sutra proper, Shankara declares that the purpose of studying Vedantic teaching is to dissolve this superimposition. Only the knowledge of the non-duality of the Self and Brahman—the great utterances like “Tat tvam asi” and “Aham Brahmasmi”—can shatter this fundamental error. We all mistakenly fuse the Self with body, senses, mind, pleasure-pain, wealth and possession. This error alone is the true cause of suffering. Vedanta’s task is to break this error asunder and bestow the knowledge of the Self’s identity with Brahman.
From delusion—from *adhyāsa*—arises *ahaṃkāra* (the ego-sense) and *mamakāra* (the sense of possession). Vedanta study exists precisely to dispel this delusion. And when the delusion dissolves, the knowledge of the Self-Brahman’s non-duality shines forth. Thus “the removal of suffering” is the *prayojana* (the purpose, the fruit), while “the knowledge of Self-Brahman non-duality” is the *viṣaya* (the subject matter). All false notions—those that breed suffering—are to be dispelled, and simultaneously, the knowledge of the Self’s unity with the Supreme is to be realized. Such is the purpose of Vedantic study. Here, “for the sake of removing this cause of suffering” indicates the *prayojana*—the fruit to be attained. And “for the sake of knowledge of the Self’s unity with the Supreme” makes clear the *viṣaya*—the subject matter itself.
So what is the purpose of this introduction, beginning with “you-and-I” and ending with “all worlds are directly perceived”? It demonstrates that all of human activity—all thought and behavior—springs from delusion and bears the mark of *ahaṃkāra*. Thus: “Aham manuṣyaḥ”—I am a man, wherein the Self is conflated with body or senses. “Aham idam”—I am this. “Mama idam”—This is mine (child, wealth, possessions, and so on).
The answer is this: through knowledge of Brahman, the root cause of life’s futility (the hollow suffering and destitution) is resolved—this is what the sutra indicates. Now, futility is constructed through the sense of being a doer and an enjoyer. And this very sense rests upon the notion of being a knower.
If such futility were truly real, it could never be destroyed by knowledge. For knowledge destroys only ignorance (*avidyā*), never what is actually real.
But if the sense of agency and enjoyment rest upon ignorance, then what the aphorist seeks to convey—that knowledge of Brahman destroys the root of suffering—becomes true.
Therefore, since knowledge can indeed destroy agency and so forth, it stands established that agency and enjoyment are in fact the products of ignorance, and the aphorist himself makes this clear when he says that knowledge of Brahman destroys suffering. Thus, to establish the meaning set forth in the aphorism, it becomes necessary to explain the nature of bondage born of delusion. And this is precisely why this opening commentary (the introduction) serves as a preamble to the entire scripture—to Vedanta itself.
The study of Vedanta begins with the aim of removing the root cause of suffering and attaining knowledge of the unity of Brahman and Atman. The root cause of suffering is the sense of “I-ness” born from ignorance—wherein a person mistakenly claims body, senses, and possessions as “I” or “mine.” If this delusion were truly real, knowledge could never erase it. But because it springs from ignorance, it can be dispelled by knowledge of Brahman. Therefore, at the very outset of the commentary, the character of ego-born bondage is explained—so that the entire discussion of Vedanta scripture may rest upon a firm foundation of understanding.
I am now unpacking Shankara’s “Yusmad-Asmat” introduction (the opening of the Brahma Sutra commentary) and explaining it in Bengali.
The aphorism: “Yusmad-asmat-pratyayagochorau visayavisayinau tamaḥ-prakashavat viruddha-svarūpau.”
Bengali meaning: “The concepts ‘yusmad’ (you, yours) and ‘asmat’ (I, mine)—these two have meanings that are utterly opposite in nature. Just as darkness and light cannot coexist, so too their essential characters are mutually contradictory.” “Yusmad” = you, yours, that is, the external. “Asmat” = I, mine, that is, the inward Self. Just as darkness and light never dwell together, so these can never merge.
The aphorism: “Asmat-pratyayagocharaḥ ātmā sarva-loka-pratyakshaḥ.”
Bengali: “That which is grasped through the concept ‘asmat’ is the Self, which is the direct experience of all conscious beings.” This means: each of us says “I am,” “I see,” “I know”—here ‘I’ is the Self itself. This Self comes directly into experience.
The aphorism: “Yusmad-pratyayagochorāḥ śarīrendriya-prāṇādayaḥ, ātmano vyāpāraḥ.”
Bengali: “That which is grasped through the concept ‘yusmad’ comprises body, senses, vital breath, and the like—the external manifestations or outer members of the Self.” This means: when I say “you are body,” “you are eyes,” “you are hands”—these are external things. They are not the Self; rather, they are the Self’s outer appendages.
The logic and intention: Shankara makes clear from the very beginning that human beings err in thinking “I am body,” “I am mind,” “my son,” “my wealth,” and so on. The true fact is this: the Self (asmat) and body-mind-matter (yusmad) are never identical. Just as light and darkness cannot merge, so too the Self and the non-Self cannot become one.
The purpose of this introduction is to refute from the outset the delusion born of egoism (I = body, senses, mind), and to demonstrate that the Self = non-dual consciousness. Body-mind-senses = yusmad, that is, the outer world, which is ever-changing. Self = asmat, which is eternal and unchanging.
Shankara draws a sharp line of demarcation from the very start: I (asmat) = the Self, the eternal conscious being. You/that (yusmad) = body, mind, senses, children, wealth, all that is external. These two are never one.
