This Upanishad, revered by scholars and spiritual seekers alike, reveals the relationship between Atman (the individual soul) and Brahman (the universal consciousness), explaining how they are interconnected through the states of consciousness and the mystical power of AUM. In this article, we will explore the Mandukya Upanishad, highlighting its teachings on the four states of consciousness (waking, dreaming, deep sleep, and transcendence) and how AUM symbolizes these states, offering a path to ultimate realization and liberation.
What is the Mandukya Upanishad?

The Mandukya Upanishad is part of the Atharvaveda and is considered one of the shortest yet most significant Upanishads in Hindu philosophy. Comprising just 12 verses, it presents a concise yet profound account of the nature of reality, the self, and the universe. The central theme of the Upanishad revolves around the symbolism of AUM, which is described as the primal sound or cosmic vibration that underlies all of creation.
The Mandukya Upanishad explores the four states of consciousness—waking, dreaming, deep sleep, and Turiya (the transcendental state)—and links them to the four phases of AUM: A, U, M, and the silence that follows the chanting of AUM. Through these teachings, the Upanishad provides profound insights into the nature of the self (Atman) and the path to spiritual liberation (moksha).
The Four States of Consciousness in the Mandukya Upanishad

One of the key teachings in the Mandukya Upanishad is the exploration of consciousness. The Upanishad describes four states of consciousness: the waking state, the dream state, the deep sleep state, and the transcendental state (Turiya), with each of these corresponding to a specific aspect of reality. Let’s delve deeper into each of these states and how they relate to the AUM symbolism.
1. The Waking State (Jagrat)
The first state of consciousness described in the Mandukya Upanishad is the waking state, or Jagrat. In this state, the individual is fully engaged with the external world through the senses. This is the state in which most people spend the majority of their time, perceiving the physical world through sight, sound, touch, taste, and smell. The waking state is associated with A (the first syllable of AUM).
In this state, the individual ego (Jiva) identifies with the body and its interactions with the world. However, the Mandukya Upanishad teaches that this state is only one aspect of the total experience of consciousness. It is an illusion in comparison to the higher, more profound states of awareness.
2. The Dreaming State (Swapna)
The second state of consciousness is the dream state, or Swapna, where the individual experiences internal, subjective realities that are detached from the external world. In this state, the individual’s senses are no longer interacting with the external world but instead with mental images, memories, and desires. Dreaming is associated with the U (the second syllable of AUM).
In the dream state, the sense of self continues to exist but in a more abstract form. The Upanishad teaches that while the dream world feels real to the dreamer, it is still just another form of illusion. The Mandukya Upanishad uses this state to show that the mind can create realities that are independent of the physical world, but like the waking state, these too are transient and illusory.
3. The Deep Sleep State (Sushupti)
The third state of consciousness described in the Mandukya Upanishad is Sushupti, the deep sleep state. In this state, the individual experiences a form of blissful ignorance, where there is no awareness of the external world, nor of the internal world. It is a state of rest and rejuvenation, free from desires and sensory perceptions. The deep sleep state corresponds to the M (the third syllable of AUM).
The individual is still present in this state, but without the consciousness of the waking world or the dreaming world. In deep sleep, the sense of individual ego fades away, and there is a temporary cessation of all mental activity. Although this state brings peace and relaxation, it is not a state of enlightenment, as the individual remains unaware of the true nature of the self.
4. The Transcendental State (Turiya)
The fourth state of consciousness is Turiya, the transcendental or fourth state. Turiya is not a state of ordinary consciousness, but rather the state of pure awareness and the experience of oneness with the universe. In this state, the individual experiences absolute peace, stillness, and the realization of Brahman, the ultimate reality.
Turiya is the state of enlightenment and self-realization, where there is no distinction between the self (Atman) and the universe (Brahman). It is the state of transcendence, beyond the dualities of the waking, dreaming, and deep sleep states. Turiya is symbolized by the silence that follows the chanting of AUM, representing the ultimate reality that underlies all states of existence.
In the Mandukya Upanishad, Turiya is described as the true self, the unchanging, eternal consciousness that exists beyond all temporary states. It is the state of ultimate liberation (moksha), where the individual experiences the realization that they are one with the universe.
The Symbolism of AUM in the Mandukya Upanishad
The Mandukya Upanishad is deeply associated with the AUM symbol, which is considered the most sacred sound in Hinduism. AUM (or OM) is not just a mantra but a representation of the entire universe and the ultimate reality. The Upanishad teaches that the four states of consciousness correspond to the four aspects of AUM: A, U, M, and the silence that follows.
1. A – The Waking State
The first syllable, A, symbolizes the waking state of consciousness, where the individual is engaged with the external world. It represents the material world and the experiences derived from the senses. The A sound is pronounced with a wide-open mouth, symbolizing the expansive nature of the waking consciousness.
2. U – The Dreaming State
The second syllable, U, symbolizes the dreaming state. It represents the internal world of the mind, where perceptions and desires shape our reality. The U sound is pronounced with the mouth slightly closed, symbolizing the inward focus and the subjective nature of the dream state.
3. M – The Deep Sleep State
The third syllable, M, corresponds to the deep sleep state, where there is no awareness of either the external or the internal worlds. It symbolizes a state of blissful ignorance and non-dualism, where the individual is free from desires and ego. The M sound is pronounced with the mouth completely closed, symbolizing the cessation of all mental activity.
4. The Silence – The Transcendental State
The silence that follows the chanting of AUM symbolizes Turiya, the transcendental state of pure awareness. It represents the ultimate reality beyond all dualities, the unchanging consciousness that is the essence of everything. This silence is not an absence but a profound presence—the eternal reality underlying all states of existence.
The Relevance of the Mandukya Upanishad in Modern Times
The teachings of the Mandukya Upanishad on consciousness and the symbolism of AUM continue to hold deep relevance today, especially in the realms of spirituality, meditation, and self-realization. Modern practitioners of yoga and mindfulness often turn to the Mandukya Upanishad to gain a deeper understanding of the nature of the self and how to transcend the limitations of the material world.
In today’s fast-paced world, the Upanishadic teachings on the four states of consciousness provide a framework for understanding the stages of consciousness that we all experience. They offer a path for cultivating higher states of awareness, ultimately leading to moksha, or liberation.
The AUM symbol remains central to modern meditative practices, particularly in mantra meditation, where repeating AUM is believed to connect the practitioner to the divine and bring about spiritual awakening. By contemplating the meaning of AUM and meditating on its symbolism, one can gradually move towards self-realization and ultimate truth.
Conclusion: The Timeless Wisdom of the Mandukya Upanishad
The Mandukya Upanishad is a deeply philosophical and spiritual text that offers profound insights into the nature of consciousness and the path to enlightenment. By exploring the four states of consciousness and understanding the symbolism of AUM, the Upanishad provides a pathway to understanding the self and realizing its oneness with the universe.
Its teachings on the nature of the self, the transcendence of dualities, and the ultimate reality continue to resonate with spiritual seekers and philosophers alike, making the Mandukya Upanishad a cornerstone of Hindu philosophy and Vedantic wisdom.
