Ignorance-Knowledge: 55

"Ātmanā ābhāsat." This means "revealed by the Self" or "illuminated in the light of the Self." This expresses the fundamental principle of Advaita Vedanta, which declares that Brahman alone is the revealer or illuminator of all things. This formula explains the relationship between the Self (Brahman) and the world or manifest objects.


Here, the Self (Ātmanā) is that pure consciousness which alone is eternal truth. Ābhāsat means "is revealed" or "is illuminated." Nothing in the world or in our experience is self-revealing. Our mind, intellect, senses, and external objects—all are illuminated and revealed through the borrowed power of that one Self's consciousness or light. This formula proves that the Self is the witness or seer, and everything worldly is merely a scene revealed in His light.


Ramana Maharshi explains this concept simply: "When you see the world, you see the reflection of the Self distorted by the mind." That is, this visible world is the distorted reflection of the Self due to the modification called mind. The world is thus in one sense not real, yet its presence is felt because it is an appearance of Brahman. Therefore, the doctrine of appearance (ābhāsa-vāda) says that creation has no beginning or end—it is an image seen in the light of eternal Brahmic consciousness.


The next stage of this realization is eternal Brahman-experience (Cira-Brahma-Anubhava). 'Cira' means eternal, 'Brahma' means supreme consciousness, and 'anubhava' means direct experience. The Self is always Brahman, therefore Brahman-experience is also eternal; only this experience remains veiled by clouds of ignorance. Just as the sun never goes out but gets covered by clouds, similarly the Self never becomes ignorant, only the obstacle to knowledge—ignorance—keeps it veiled. Shankaracharya says, "Knowledge is not newly produced, but rather the removal of covering"—that is, knowledge is not creation, it is mere revelation. Ramana Maharshi says, "You are always experiencing the Self; only you do not recognize it." That is, Self-experience is always ongoing, but we mistakenly take it for experience of external objects. Swami Chinmayananda says, "Brahman is not an experience in time; it is timeless awareness illumining all experiences." Therefore, eternal Brahman-experience means not acquiring something new, but learning to consciously experience what is always happening—where the same consciousness remains unwavering through waking, dreaming, and deep sleep states.


The culmination of this experience is Self-Brahman identity (Ātma-Brahma-Tādātmya), that is, the inseparable oneness of Self and Brahman. This very principle is declared in the great statements of the Upanishads—"Ahaṁ brahmāsmi" (I am Brahman), "Tat tvam asi" (Thou art That), "Ayam ātmā brahma" (This Self is Brahman), "Prajñānaṁ brahma" (Consciousness itself is Brahman). The difference between individual soul and Brahman is created only by ignorance. Just as the space inside a pot and the space outside are actually one, but the walls of the pot make them seem separate, similarly the limiting adjuncts of body-mind make the individual soul seem separate from Brahman. When these adjuncts are removed, the Self knows itself as Brahman—this is identity (tādātmya).


The word Tādātmya derives from the Sanskrit roots "tad" (that) and "ātma" (self)—from these two elements, meaning "I am that Self" or "inseparable oneness." Its philosophical significance is that when two entities are so inseparable that they cannot be thought of separately, that state is called tādātmya.


In Advaita Vedanta, the term 'tādātmya' is used to understand the relationship between the individual soul (personal self) and the Supreme Self or Brahman (all-pervading consciousness). According to Advaita, the individual soul and Brahman are actually one and identical, but due to ignorance (avidyā) the notion of difference or separateness between them has arisen. This sense of difference is the root of worldly bondage. And when this ignorance is removed, the individual realizes its true nature—it is nothing other than Brahman.


At the heart of this doctrine lie the great statements of the Upanishads—

"Tat tvam asi" (Chandogya Upanishad 6.8.7)—"Thou art That,"

"Ahaṁ brahmāsmi" (Brihadaranyaka Upanishad 1.4.10)—"I am Brahman,"

"Ayam ātmā brahma" (Mandukya Upanishad 1.2)—"This Self is Brahman,"

and "Prajñānaṁ brahma" (Aitareya Upanishad 3.3)—"Consciousness is Brahman."


These four statements all declare that there is no real difference between Self and Brahman—their identity or non-difference is infinite and unfailing.


To explain the identity of Brahman and the individual soul, Shankaracharya has given multiple illustrations. For instance, the space inside a pot (ghatākāśa) is not different from the space outside (mahākāśa)—it only seems separate due to the limitation of the container. Similarly, the limitations of body and mind have confined the individual soul; when the adjunct is removed, that very soul is Brahman—all-pervading, formless, non-dual.


Tādātmya is not merely a theoretical concept; it is a self-experience. When the seeker knows, "I am not the body, not the mind, not the senses, I am eternal consciousness," then he experiences complete unity with Brahman. This is not a new experience, but the revelation of what was always true. Therefore Shankaracharya says, "Knowledge does not produce anything new; only the Self-nature is revealed."


As a result of this realization, all sense of doer-enjoyer, pleasure-pain, individual-world disappears. Then it is seen—the Self that is within me is the same Self within all beings; the consciousness that is the foundation of my feelings is present throughout the entire universe. This very state is Brahman-realization or direct knowledge.


Ramana Maharshi says, "When the 'I'-thought disappears, what remains is not void but pure Being—the same Self in all beings. That is Tādātmya." That is, when ego-sense dissolves, what remains is not emptiness, but pure existence—that Self which exists identically everywhere. Swami Vivekananda expressed this same truth in modern language: "Each soul is potentially divine; the realization of this identity is religion." And Swami Chinmayananda explained: "Tādātmya is not union of two, but the discovery that there were never two."


Tādātmya is not a joining—joining would require assuming two entities; but in tādātmya there is fundamentally only one entity, eternal consciousness, within which there is nothing else. Advaita declares this very truth—"ekam evādvitīyam"—the one and non-dual Brahman alone exists everywhere.


When the seeker realizes this identity, then his liberation occurs. Then nothing 'other' remains—neither God, nor world, nor individual soul—all together form one Brahmic consciousness. Then the Upanishadic declaration becomes true—"brahmavit brahmaiva bhavati"—he who knows Brahman becomes Brahman itself.


This experience or realization of identity is the ultimate culmination of Advaita Vedanta—where the enlightened person sees that all differences are false, all forms are the play of one consciousness, and the Self is Brahman, Brahman is the Self—indivisible, eternal, and complete.


"Yathā gaganapatayor ekatā, tathaika yaṁ jīvabrahmaṇoḥ"—that is, "Just as there is unity between sky and cloth, so there is oneness between individual soul and Brahman." This statement is not an ancient Upanishadic mantra or verse. It is a philosophical analogy or reasoning (Analogy) of Advaita Vedanta, used to refute a mistaken notion regarding difference and non-difference. This type of analogy is commonly used in discussions of māyā and Brahman. It essentially establishes a contrary argument by showing that calling two different things (sky and cloth) one is impossible.


This analogy is based on the idea where space is sometimes imagined as material (such as sky-blue). This analogy is used to convey apparent unity or non-difference between contrary objects.


Sky-blue refers to the perception or illusion of the blue color of the sky. From the perspective of Vedanta or physics, the sky or outer space is essentially immaterial and colorless. The sky has no color of its own. The blue color we see in the sky is actually not the sky's own color. This is the result of the scattering (Rayleigh scattering) of sunlight coming through the atmosphere. When light hits particles in the atmosphere, blue wavelength light scatters the most, making the sky appear blue to us. For this reason, thinking of the sky as blue or imagining the sky as a blue-colored object is an illusion or false perception.


In this analogy, sky-blue is an example that helps explain how an immaterial and colorless entity is mistakenly considered material or qualified. The sky-blue analogy is used to convey such a false notion, where what does not exist is thought to exist. The analogy wants to show how people mistakenly impose material or limited qualities (such as blue color) on an immaterial entity (like the infinite nature of Brahman). Just as sky-blue is an illusion that needs to be removed, similarly imposing limitations, colors, or forms on the infinite oneness of individual soul and Supreme Self is also an ignorance-born illusion.


a. Disproving Difference or Disproving the Analogy: This analogy is first not accepted, but refuted. Sky (gagana, which is infinite, indivisible, immaterial) and cloth (pata, which is finite, inert, and a different object)—real unity between these two different objects is impossible. That is, there cannot be unity between two different and independent objects. Using this logic, Advaita Vedanta explains—if individual soul and Brahman were two independent entities, then unity or non-dual knowledge between them would be impossible. Since liberation is unity (non-dual knowledge of individual soul and Brahman), and unity between two different objects is impossible, this proves—individual soul and Brahman are not different—the individual soul and Supreme Self cannot be inherently different like sky and cloth.


b. Apparent Oneness: According to another interpretation, this can be understood to create the illusion of apparent unity between two objects. For instance, there might be apparent similarity between the colors of sky and cloth, but their essences are different.


From this perspective, even if unity is seen between individual soul and Brahman, until the adjuncts are removed, this unity seems like an illusion. This formula first presents a false analogy, so that the impossibility of that analogy can prove that if individual soul and Brahman were inherently different, liberation would be impossible. Since liberation is possible, it is proven that individual soul and Brahman are one and identical. In Advaita Vedanta, such analogies are often used to prove difference impossible in order to establish non-dual knowledge.


Swami Vivekananda explains this truth in modern language: "Each soul is potentially divine; the goal is to manifest this divinity within." According to Ramana Maharshi, "When the ego dies, what remains is not a void but pure Being—the Self, which is Brahman." That is, when the ego is erased, what remains is not emptiness, but eternal consciousness—that one Self-Brahman.
