Ignorance-Knowledge: 54

The Fourth never enters into the phenomenal world, nor does it ever abandon it. This means that the Fourth is such an eternal being that it is completely free from the illusions created by worldly duality, diversity, and māyā. It neither actively participates in the world nor remains entirely detached. Rather, it is like a constant light that illuminates all states while remaining established in its own nature. It illuminates all worldly experiences and knowledge, but never becomes the object of any experience or knowledge itself.


For this reason, the Fourth is called 'prapañcopaśama.' 'Prapañca' refers to all worldly duality, diversity, and illusory manifestations. 'Upaśama' means stillness or dissolution. That is, the Fourth is such a state where all duality, conflict, and delusion disappear, and the experience of supreme peace and unity is established. This is that ultimate spiritual state where the soul manifests in its true form, liberated from all bonds. It is not merely a philosophical concept, but the name of a profound experience attainable through spiritual practice—where the individual is situated at the very center of existence and becomes one with the Supreme Truth.


The Māṇḍūkya Upaniṣad, one among the ten principal Upanishads, is particularly renowned for its profound philosophical insights despite its brevity. Not only has it gained supreme importance in modern Vedantic thought, but various sages and scholars have made it even more influential through their commentaries and analyses. The Upanishad provides a detailed description of the four states of consciousness—waking (vaiśvānara), dream (taijasa), deep sleep (prājña), and the Fourth—establishing a fundamental foundation on the path to Self-realization.


Swami Chinmayananda, an influential Vedantic teacher, has expressed the central concept of the Māṇḍūkya Upaniṣad in remarkably concise yet profound terms: "The first three are experiences in time; the fourth is timeless Being. Knowing it is liberation." This statement brilliantly captures the essential teaching of the Upanishad. Here, the first three states—waking, dream, and deep sleep—are considered experiences bound by time. In the waking state, we experience the external world through the five senses. In the dream state, the mind creates and moves within an internal world. In deep sleep (suṣupti), all kinds of differentiation dissolve and the mind remains completely peaceful, though a subtle layer of consciousness still exists. All three of these states are changeable and relative, connected with the sense of ego.


On the other hand, the Fourth transcends these three states—it is an eternal and undivided being. Beyond space, time, and causation, it is the direct experience of nirguṇa Brahman. According to Swami Chinmayananda, knowing or realizing this Fourth state is true liberation. This is not a new experience, but rather a return to our true nature, which was always present but veiled by māyā. The Fourth is that pure consciousness which illuminates all experiences but remains unaffected by any experience. It is not merely a state, but the foundation of all states and their witness.


Swami Swaroopananda has added another important dimension to the interpretation of the Māṇḍūkya Upaniṣad. He says, "Mandukya is not about four separate states but about realizing that you, the awareness, are untouched by waking, dream, or sleep." Swami Swaroopananda's statement highlights another fundamental truth of the Upanishad. It is not about four separate entities of consciousness, but about the realization of that awareness—which remains unaffected in any state of waking, dream, or deep sleep.


According to this interpretation, our true nature is that 'awareness' or 'seer' which merely observes the changes in these three states. We identify ourselves so deeply with worldly experiences that we forget we are actually only witnesses to these experiences, not part of them. In the waking state, we think we are the body and mind; in the dream state, we are characters in the dream; and in deep sleep, we experience a void. But behind each of these experiences exists an unchanging consciousness that illuminates all these changes. This unchanging consciousness is called the Fourth. It cannot be obtained by adding or subtracting anything; it is only a matter of realization.


The Māṇḍūkya Upaniṣad follows a special method to provide this realization. It explains the four states of consciousness through the sacred syllable 'Oṃ' (AUM). The letter 'A' signifies the waking state, the letter 'U' represents the dream state, and the letter 'M' indicates the deep sleep state. The silent portion of 'Oṃ' or the unstruck sound represents the Fourth state. This profound analysis helps the human mind penetrate deep into its own nature and shows it the way to transcend its limitations and merge with infinite consciousness.


In the modern age, where psychology and neuroscience strive to unravel the mysteries of consciousness, this ancient wisdom of the Māṇḍūkya Upaniṣad remains relevant. It is not merely a religious or spiritual text, but a practical guide to understanding the nature of human consciousness and Self-realization. Its teaching helps us delve deep into our inner world and connect with our true being, showing the path to liberation from all suffering and limitation. This Upanishad is therefore not just an ancient text, but an eternal answer to humanity's timeless quest.


The Self is one, eternal, without a second—its manifestation is the world, taijasa, and prājña. But when the mind transcends these three and establishes itself in the Fourth, only then does the Self realize its true nature—Brahman in the form of existence-consciousness-bliss. This realization is the supreme teaching of Māṇḍūkya, where the "four-footed Self" ultimately dissolves into non-dual consciousness, and only that Truth remains—"ekamevādvitīyam," one and without a second.


The individual soul constantly moves through these four states—waking, dream, sleep, and the possibility of Fourth experience. But the nature of the soul never changes—that same consciousness continues through every state. Just as the sun shines during the day, hides at night, becomes obscured by clouds—yet the sun remains unchanged.


However varied the world may be, Brahman alone is the only eternal truth (Nitya-Satya). All these changes, forms, emotions, and actions belong to Brahman. The Upanishad therefore firmly declares—"ayam ātmā brahma"—this Self is Brahman, this world is the manifestation within Brahman. Whatever is seen, heard, or thought—all are merely waves of that one consciousness.


When this realization awakens in the seeker's heart, the world no longer remains "other" to them; in all existence they continue to recognize themselves. Then in their understanding, "sarvaṃ hi etad brahma" (Māṇḍūkya Upaniṣad, Mantra 2)—this one statement becomes the eternal truth—all is Brahman, nothing exists except Brahman.


The Self is eternally illuminated, self-luminous (Svayam-Prakāśa). The veiling power can never obscure it, just as darkness can never touch the sun. The sun is not "illuminated"; it is light itself; only when the eyes are closed is its light not perceived. Similarly, the Self is never covered by ignorance; only the mind appears veiled by the reflection of avidyā. Both ignorance and its breaking occur at the level of that mind—not in the Self.


In Advaita Vedanta, three profound concepts interconnectedly explain the unity of Self, world, and Brahman—ābhāsa-vāda, eternal Brahman-experience, and Self-Brahman identity. These three concepts are essentially three aspects of one consciousness—reflection, realization, and unity.


According to ābhāsa-vāda (Appearance Theory), the world is not a real creation; it is a reflection of Brahman-consciousness, an illusory manifestation. 'Ābhāsa' means reflection or image, like seeing the shadow of a face in a mirror—it is not real, yet without the face it would not be possible. Brahman is that face, and the world is its reflection. In the Vivaraṇa school established by Padmapādācārya and Prakāśātman, it is said, "citir bhāse viśvamidam"—this world is merely a reflection of consciousness. The essence of this statement is based on a famous verse from the Kaṭha Upaniṣad (2.2.15) and Muṇḍaka Upaniṣad (2.2.10): "tameva bhāntam anubhāti sarvam. tasya bhāsā sarvamidam vibhāti." That is, when that Self is illuminated, everything becomes illuminated following it. In its light, this entire world is illuminated.


This sūtra establishes the all-pervasiveness of Brahman and the self-luminosity of the Self. Here, Cit is pure consciousness or Brahman. This alone is the only eternal and self-luminous being. Bhāse means in the light, in manifestation, or in appearance. Viśvamidam means this entire visible world.


This world or any object we see is not self-luminous. Our mind, intellect, and senses—everything becomes illuminated and functional only in the light of that one Cit or consciousness. This proves that the world is not real, but merely a reflection superimposed upon Cit.


"Ātmanā ābhāsata"—through the reflection of the Self, the appearance of manifold phenomena occurs. This is a conclusive statement used to explain the self-luminous nature and power to manifest everything of Brahman or Self. The essential meaning of this statement is found in Upanishads like the Kaṭha, Muṇḍaka, and Śukla Yajurveda. For instance: "tameva bhāntam anubhāti sarvam. tasya bhāsā sarvamidam vibhāti." That is, when that Self is illuminated, everything becomes illuminated following it. In its light, this entire world is illuminated. This famous mantra is found in almost identical form in three principal Upanishads, proving its importance.


Kaṭha Upaniṣad—2.2.15. Muṇḍaka Upaniṣad—2.2.10. Śvetāśvatara Upaniṣad—6.14.


This mantra establishes the nature of Brahman and the principle of its self-luminosity.


The Self's self-luminosity (tameva bhāntam anubhāti sarvam)—Bhāntam: Here the Self or Brahman is that one being who is self-luminous. Nothing else is needed for its manifestation. Anubhāti sarvam: "Anubhāti" means to be illuminated following. This means that everything else in the world that is illuminated—sun, moon, stars, fire, or our mind and intellect—all are illuminated by borrowing the power of Brahman's light. Brahman is the primary illuminator of them all.


The world as reflection of Brahman (tasya bhāsā sarvamidam vibhāti)—Tasya bhāsā: 'In his light'—this portion ultimately declares that this entire visible world (sarvamidam) that we see (vibhāti) has its fundamental basis in Brahman's consciousness.


Just as a room is illuminated by sunlight; the room is not self-luminous—similarly, this material world is illuminated and remains active only in the consciousness-light of Brahman. This mantra highlights that supreme truth of Advaita Vedanta that this world is not real, but Brahman alone is the only reality. The world is a reflection or apparent manifestation (Māyā) illuminated in Brahman's light.
