Gauḍapāda's commentary on the seven verses of the Māṇḍūkya Upaniṣad. Establishes the four states of consciousness and their correspondence with the four quarters of Oṃ — the framework for all that follows.

The first chapter of the Kārikā is the most accessible — it stays close to the Māṇḍūkya Upaniṣad text it is commenting on. Gauḍapāda elaborates on the four states (waking, dream, deep sleep, and the fourth beyond all three) and maps them onto the four parts of the syllable Oṃ.
The key move of the first chapter is the comparison between waking and dream. In dream, you experience a world — people, places, conversations, emotions. That world feels completely real while you are in it. When you wake, you recognise it was a dream — it had no independent existence outside your experiencing of it. The waking world, Gauḍapāda points out, has the same structure. The objects of waking are perceived only within consciousness. Their independent existence beyond consciousness has never been demonstrated.
This does not mean the waking world is unreal in the way a dream is unreal. The distinction Gauḍapāda is drawing is subtler: both waking and dream are modifications of consciousness. The question the first chapter sets up — which the later chapters answer — is: what is the consciousness within which both arise? That is Turīya. That is Brahman.
The technical focus of the Āgama-prakaraṇa is the threefold analysis of consciousness: viśva (waking, outward-directed, identifying with the gross body), taijasa (dream, inward-directed, identifying with the subtle body), and prājña (deep sleep, unified, undifferentiated). Turīya is the fourth — not a state but the ground.
Gauḍapāda adds a structural insight beyond the Upaniṣad: the three states are related not just as sequential experiences of one individual self but as analogues to different modes of cosmic consciousness. At the individual level, Viśva/Taijasa/Prājña. At the cosmic level, Virāṭ/Hiraṇyagarbha/Īśvara. The individual and cosmic are both appearances within the one non-dual Turīya consciousness.
Verses 24–29 of this chapter introduce the Oṃ meditation directly: A corresponds to waking (common ground — both arise and both share the quality of being first), U to dream (elevation — both are intermediate, subtler than the gross), M to deep sleep (measure — both involve the merging of distinctions). The silence after M is Turīya — amātra, beyond measure, beyond all correspondence.
The philosophical crux of Chapter 1 is the identity claim between individual consciousness states and cosmic-consciousness levels. This is not an analogy but an identity — Viśva and Virāṭ are the same consciousness appearing at different scales. Gauḍapāda establishes this through the grammar of the Upaniṣad itself: in the Māṇḍūkya, both individual and cosmic are described with the same terms without distinction. Śaṅkara in his Bhāṣya on this chapter makes the identity explicit: the three — Viśva, Taijasa, Prājña — are not three different entities but Brahman appearing through three limiting adjuncts (upādhis).
The chapter's most technically important verse is 1.6: sarvasyādiḥ prabhaviṣṇuśca devaḥ — 'Turīya is the lord who is the source and ground of all.' The term prabhaviṣṇu (all-pervading, from which all arises) is a direct claim that Turīya is identical with Brahman as described in the Upanishads — not a psychological state but the ultimate ontological ground.
