“Nirvana Shatakam” is a unique hymn of self-awakening in Advaita Vedanta—where the Self is identified not as any visible entity, not as any reflection of thought, but as Pure Consciousness, which is never born, never dies, never changes. The Self liberates itself from the confines of body, mind, senses, and elements to awaken in its own nature of consciousness. “Nirvana Shatakam”—meaning “Six Verses of Liberation”—is sometimes also known as “Atma Shatakam.” It is a lyrical text of self-realization, considered a summary of Advaita philosophy.
Within the very first verse lies hidden the heart of all Advaita philosophy. Shankaracharya composed this hymn in a philosophical context where human self-identity was confined to body and mind. He sought to break these false limitations through the Upanishadic method of “neti neti”—meaning “not this, not that.” When his guru Sri Govindapada asked him—”Ko’si?”—”Who are you?”—Shankaracharya responded with six verses, each of which liberates the Self from body, mind, senses, and nature at different levels, establishing it in its true form.
In the first verse, he systematically breaks down five coverings or limiting adjuncts (Upādhi).
First, *manobuddhyahaṅkāracittāni nāhaṅ*—I am not the mind (manas), I am not the intellect (buddhi), I am not the ego (ahaṅkāra), I am not the memory (citta). That is, I am not those mental processes that form personality through thinking, reasoning, memory, or self-reflection. Mind comes and goes; thoughts arise and dissolve; but that being which witnesses these changes never itself changes—that is I.
Second, *na ca śrotrajihve na ca ghrāṇanetre*—I am not the auditory sense, not the tongue, not the olfactory sense, not sight either. The senses are merely instruments of connection with the world, but the Self is only a witness to this connection. The Self neither sees nor hears, but the very possibility or connection of seeing and hearing exists through it alone.
Third, *na ca vyoma bhūmir na tejo na vāyuḥ*—I am not space, earth, fire, or air. That is, I am not any element of those five elements (pañcamahābhūta) that constitute the body. When the body dissolves, the elements return to nature, but the Self remains unaltered.
Fourth, after all these negations, Shankara says the Self is *cidānandarūpaḥ*—whose very form is consciousness (Cit) and bliss (Ānanda). Cit means that illuminated awareness which is the foundation of every experience; Ānanda means that completeness which is self-sufficient within itself. This consciousness never “knows something,” but rather is “the light of all knowing”—just as the sun does not illuminate anything, but is light itself, so the Self is not knowledge, but the foundation of knowledge’s existence.
Finally, he says, *Śivo’ham Śivo’ham*—”I am Shiva, I am Shiva.” Here “Shiva” is not a mythological deity, but supreme consciousness (Paramacit)—that all-pervading, indestructible, unchanging being. This repetition of “Śivo’ham” is not merely linguistic; it is the echo of the Self’s self-vision—as if realization is entering ever deeper levels.
Shankaracharya thus transcends all levels of “body,” “mind,” “senses,” and “five elements” to establish the Self in its unconditional existence. Each verse of this hymn begins with “nāhaṅ” and ends with “Śivo’ham”—like an ascent from “untruth” to “truth”: from nāhaṅ (I am not) to ahaṅ (I am), from that to Śivo’ham (I am Shiva).
This realization is the essence of Advaita Vedanta—Self and Brahman are one, world and consciousness are inseparable. The verse “manobuddhyahaṅkāracittāni nāhaṅ…” resonates this knowledge, leading to that self-realization where one can declare—I am not the body, I am not the mind, I am not the senses; I am that pure consciousness, I am that supreme bliss, I am that imperishable Shiva—cidānandarūpaḥ Śivo’ham Śivo’ham.
A “cognitive event” refers to a moment when some experience or thought consciously manifests within the mind. It is not mere information processing, but rather a spontaneous arising of consciousness where knowing, feeling, or perceiving—all these mental activities become apparent in the light of reality. That is, a cognitive event is that subtle point where consciousness knows something within itself.
Philosophically, it is an “intentional act of consciousness”—that is, a directional activity of consciousness always aimed toward some object or idea. In Edmund Husserl’s phenomenology, this concept is primarily explained through the noesis-noema dialectic—where noesis means the act of knowing, and noema means the known object. Every cognitive event is therefore a specific directional state of consciousness; consciousness is never empty, but always directed “toward something” (about something).
In psychological terms, a cognitive event is the manifestation of thoughts, perceptions, decisions, or memories occurring at various levels of the mind. When we perceive something, suddenly get an idea, or reach a conclusion, then the nervous system’s activity becomes transformed into the light of consciousness—that moment is the cognitive event. At the neurological level it is biological brain activity, but at the experiential level it is a conscious expression where brain activity becomes self-aware as “I know.”
In Advaita Vedanta and Kashmir Shaiva philosophy, this concept takes on deeper meaning. Here, a cognitive event is not some separate psychological process, but consciousness’s return to itself—consciousness knows itself, perceives its own manifestation within itself. In the Spanda theory of Kashmir Shaiva philosophy, it is said that every vibration of consciousness is a kind of cognitive event—a momentary oscillation where Shiva recognizes himself as his own manifestation (Śakti).
Abhinavagupta called this event of self-realization *vimarśa*—that self-awareness of consciousness where knowing and the object of knowing merge into one. According to him, “illumination” (*prakāśa*) is consciousness’s light, and “reflection” (*vimarśa*) is that light’s turning back upon itself. When this turning back occurs, then a cognitive event happens—knowledge is no longer related to any external object, but perceives itself within itself.
Thus, from the perspectives of phenomenology, psychology, and Tantra-Vedanta, a cognitive event is a fundamental consciousness-event—consciousness’s self-manifestation within a single moment. Here the triad of knower, knowledge, and known dissolves to take form in consciousness’s singular vibration. Then knowing does not mean learning something, but consciousness’s own radiance blazing forth. In this state, knowledge is no longer an action—it is existence’s own manifestation, where consciousness declares: “Aham”—I am, I know, I am the very form of that knowledge.
Phenomenology is a philosophical method that analyzes the nature of human experience, consciousness, and perception. Its main purpose is to understand reality or objects not from “outside” but as they appear within consciousness. That is, phenomenology is not an external explanation of reality; it dives into experience to see—”what is the nature of that seeing or feeling by which we see, feel, and understand the world?”
The modern founder of this philosophy was German philosopher Edmund Husserl (1859–1938). According to him, philosophy’s real task is not to understand the world, but to understand how the world manifests in our consciousness. Husserl says, “The fundamental question of our knowledge or experience is—how do things appear to our consciousness?” Therefore, at the center of philosophy should be pure analysis of experience—without any assumptions, religious beliefs, or scientific theories.
The first fundamental concept of phenomenology is Intentionality—that is, all consciousness is always directed toward something. When we think, see, or feel, consciousness never remains in an empty state; it is always “facing” toward some subject—I see this tree, I feel some pain, I think a thought. Thus consciousness means not just “being conscious” but “being conscious of something.” This relationship creates the bridge between consciousness and object, interior and exterior.
Husserl’s second important concept is Epoché or Bracketing. He says when we analyze experience, we should suspend questions about the truth of external reality. For example, if we say “a red flower,” phenomenology would say—”whether the flower actually exists outside or not,” set that aside for now; rather see how the flower is present in my consciousness—color, fragrance, shape, memory—it appears to me as a “flower” through the synthesis of all these sensations. This way we arrive at “pure description of experience,” where consciousness’s manifestation is illuminated in its own light.
One of Husserl’s famous statements was—”Zurück zu den Sachen selbst!”—meaning “Back to the things themselves!” That is, abandoning concepts, explanations, and theories, return to direct experience. We usually see things through the filter of our concepts, but phenomenology teaches how to remove that filter and see what is truly present in experience.
Husserl’s student Martin Heidegger gave this concept an existentialist dimension. He says phenomenology is not merely analysis of consciousness; it is inquiry into human existence (Being). Humans don’t just see; they are “being-in-the-world.” Therefore consciousness means not just seeing or knowing, but “being in the world,” “constructing meaning,” and “gaining experience of being.”
Later, Maurice Merleau-Ponty developed phenomenology as a philosophy of body and perception. According to him, experience is not just mind, but touching the world through the body. The body is that living bridge through which world and consciousness relate to each other. Jean-Paul Sartre transformed this current into existentialism, saying that human freedom, responsibility, and meaning-construction are all embedded within the structure of consciousness itself.
The influence of phenomenology has thus spread not only in philosophy but into psychology, literature, aesthetics, sociology, even consciousness studies. It teaches—reality is not something existing outside; rather, the way we feel, see, and interpret is what constitutes reality for us.
In simple language, phenomenology says—”The world is not as it is, but as I experience it, that is how the world exists for me.” Therefore phenomenology is pure description of experience and science of consciousness—where truth means not external proof, but inner evidence—that is, truth’s awakening within consciousness itself.
Yogacara or Vijñānavāda is that branch of Buddhist philosophy which has conducted the most profound psychological and metaphysical analysis of the nature of consciousness and experience. This current of Mahayana Buddhism is known in the history of Indian thought as “consciousness-only-ism”—a perspective that declares all existence is actually consciousness’s projection; whatever we perceive is not external objects but consciousness’s own internal reflection.
