The Mandukya Upanishad (माण्डूक्योपनिषद्)

The Mandukya Upanishad is the shortest primary Upanishad, consisting of only 12 prose verses. Despite its brevity, traditional commentators (including Gaudapada, who wrote the famous *Mandukya Karika*) consider it the most complete summary of Vedanta philosophy. It explains the sacred syllable OM and maps it directly to the states of human consciousness.

Sources and Editorial Approach

The information presented on this page is compiled from standard Sanskrit manuscripts, Gita Press editions, and critical academic compilations such as those from the Bhandarkar Oriental Research Institute (BORI). We prioritize accuracy and translation alignment with classical commentators (such as Adi Shankaracharya, Sayana, and Ramanujacharya) rather than modern interpretations.

1. Waking State (जाग्रत् — वैश्वानर)

Quarter of Atman: First Quarter (Prathama Pada)

AUM Letter: 'A' (अकार)

Consciousness: Outward (Bahish-prajna)

Experience: Gross Physical (Sthula)

Overview & Philosophy

The waking state is named Vaishvanara. In this state, consciousness is directed outward. The individual interacts with the gross material world using nineteen channels: the five senses of perception (Jnanendriyas), the five organs of action (Karmendriyas), the five vital breaths (Pranas), and the four inner mental instruments (Antahkarana: Mind, Intellect, Ego, and Memory). It represents the objective world of physical sensation.

2. Dreaming State (स्वप्न — तैजस)

Quarter of Atman: Second Quarter (Dvitiya Pada)

AUM Letter: 'U' (उकार)

Consciousness: Inward (Antah-prajna)

Experience: Subtle/Mental (Pravivikta)

Overview & Philosophy

The dreaming state is named Taijasa (the luminous). In svapna, the external physical channels are inactive, and consciousness is directed inward. The mind creates its own space, projecting subtle images and situations based on memories, desires, and experiences gathered during the waking state. The dreamer experiences joy, fear, and sorrow in a subjective, self-created environment.

3. Deep Sleep State (सुषुप्ति — प्राज्ञ)

Quarter of Atman: Third Quarter (Tritiya Pada)

AUM Letter: 'M' (मकार)

Consciousness: Unified (Prajna-ghana)

Experience: Blissful (Ananda-bhuk)

Overview & Philosophy

Deep sleep is named Prajna. It is a state where the sleeper has no dreams and desires no objects. Senses and mind dissolve temporarily into a unified mass of undifferentiated consciousness (Prajna-ghana). This state is filled with natural peace and bliss (Ananda). It represents the causal state where all external subject-object dualities collapse into latency.

4. The Fourth State (तुरीय — अद्वैत)

Quarter of Atman: Fourth Quarter (Chaturtha Pada)

AUM Letter: Silence (Amatra)

Consciousness: Absolute/Transcendental

Experience: Non-dual (Advaita)

Overview & Philosophy

The fourth state is Turiya (literally, "the fourth"). It is not a state of subjective or objective experience, nor is it deep sleep. It cannot be seen, spoken of, grasped, or thought of. It is the unconditioned, pure, peaceful, auspicious, and non-dual (Advaita) essence of the Self (Atman) that underlies and observes the other three states of consciousness. Realizing Turiya constitutes ultimate liberation (Moksha).
