The second half of the Upaniṣad: the map of the Ātman is laid over the map of sound. so 'yam ātmā adhyakṣaram oṁkāraḥ — "this Ātman, taken on the side of the syllable, is Oṁkāra": what was investigated as consciousness (the four pādas) is now given as sound — so that contemplation may have something to hold on to: a state cannot be seized, a syllable can be pronounced. adhimātram — "on the side of the measures": pādā mātrā mātrāś ca pādāḥ — "the quarters are the measures and the measures are the quarters": the correspondence is two-way and leaves no remainder: a-kāra, u-kāra, ma-kāra — three sounds fused into "Oṁ".
Thus the Māṇḍūkya builds a bridge between the Praśna (three mātrās of Oṁ — three worlds) and itself: for her the three measures are the three states of consciousness. Oṁ turns out to be a portable map of the whole inner universe: uttering A-U-M, one travels from waking through dream to the depth — and further, into the fourth of which the last mantra will speak: into the measureless.
Here lies the foundation of the whole practice of the praṇava: the japa of Oṁ is not a droning of sound but the passage of the Ātman through its own storeys with the Name for a banister. The Gītā (8.13) gives this technique for the hour of departure; the Māṇḍūkya gives it for every day: the syllable, known in this way (ya evaṁ veda — the refrain of the following mantras), ceases to be a sound and becomes a stair.
