Mandukya Upanishad: Om and the Four States of Consciousness

Introduction to the Mandukya Upanishad

The Mandukya Upanishad is the shortest of all the principal Upanishads, containing only twelve verses, yet it is considered one of the most profound and significant. It belongs to the Atharva Veda and focuses entirely on the sacred syllable Om and its relationship to the four states of consciousness. The great philosopher Adi Shankaracharya held this Upanishad in the highest esteem, stating that it contains the essence of all Vedantic teachings. The Mandukya Upanishad begins with the declaration that Om is everything. All the past, present, and future are Om. Whatever transcends time is also Om. This statement establishes Om as the ultimate symbol of the absolute reality. The Upanishad then correlates the four elements of Om, namely a, u, m, and the silence after, with the four states of consciousness: waking, dreaming, deep sleep, and the transcendental state of turiya.

The First State: Waking Consciousness

The first state of consciousness is called jagrat or the waking state. In this state, consciousness is directed outward through the senses. We experience the world of objects, perceive through the five senses, and engage in various activities. The mind is active, processing sensory information and interacting with the external environment. In this state, we identify with the physical body and the ego, experiencing ourselves as separate individuals in a world of separate objects. The Mandukya Upanishad correlates this state with the letter a, the first component of Om. The letter a represents the beginning, just as the waking state is the starting point of our daily experience. The deity who presides over this state is Vishva, who experiences the gross world through the senses. The waking state is characterized by the experience of gross objects and the consciousness of individuality.

The Second State: Dreaming Consciousness

The second state is called svapna or the dreaming state. In this state, consciousness turns inward and creates its own world of dreams. The senses are withdrawn, but the mind remains active, constructing a reality based on past impressions and desires. In dreams, we experience a world that seems real while we are in it, but upon waking, we recognize it as unreal. This state demonstrates the creative power of the mind and the relative nature of reality. The Mandukya Upanishad correlates this state with the letter u, the second component of Om. The letter u represents the middle or the process of development, just as the dreaming state is intermediate between waking and deep sleep. The deity who presides over this state is Taijasa, who experiences the subtle world of mental impressions. The dreaming state teaches us that reality is not limited to the physical world and that consciousness can create its own experiences.

The Third State: Deep Sleep

The third state is called sushupti or the deep sleep state. In this state, both the senses and the mind are completely withdrawn. There are no desires, no dreams, and no thoughts. The individual enters a state of unified consciousness where the distinction between subject and object disappears. This state is characterized by bliss, peace, and the absence of all suffering. However, it is a state of ignorance because the individual is not aware of this bliss. The Mandukya Upanishad correlates this state with the letter m, the third component of Om. The letter m represents the end or the culmination, just as deep sleep is the culmination of the natural cycle of consciousness. The deity who presides over this state is Prajna, who experiences the unified bliss of ignorance. The deep sleep state gives us a glimpse of the bliss that lies beyond all mental activity and sensory experience.

Om is the bow, the self is the arrow, and Brahman is the target. One should aim at Brahman with concentration and become one with it, just as the arrow becomes one with the target. - Mandukya Upanishad

The Fourth State: Turiya

The fourth state is called turiya, which means the fourth. It is not a state of consciousness like the other three but the underlying reality that makes all states possible. Turiya is the pure consciousness that is present in the waking, dreaming, and deep sleep states as their witness. It is beyond the senses, beyond the mind, beyond all distinctions. Turiya is described as non-dual, peaceful, blissful, and without a second. It is the self, the atman, which is identical with Brahman. The Mandukya Upanishad correlates turiya with the silence that follows the chanting of Om. Just as the three letters a, u, and m merge into the silence that follows, the three states of consciousness merge into turiya. Turiya is not experienced as an object; it is the subject, the knower, the witness of all experiences. Realizing turiya is the goal of all spiritual practices, for it is the realization of one's true nature as the supreme self.

The Significance of Om

The Mandukya Upanishad teaches that Om is not merely a symbol but the very sound of the absolute reality. Meditating on Om with an understanding of its four components leads to the realization of the self. The syllable Om encompasses all speech, all sounds, and all knowledge. It is the foundation of all mantras and the essence of the Vedas. The practice of meditating on Om is a direct path to self-realization. By contemplating the relationship between Om and the four states of consciousness, the seeker gradually transcends the identification with the body, mind, and ego and awakens to the true self. The Mandukya Upanishad concludes with the declaration that the one who knows this truth attains the supreme goal of life. This Upanishad remains a vital text for all spiritual seekers, offering a clear and systematic path to the highest realization.
