Source: Atman as the Pranava - Mandukya Upanishad
The Atman is the content of the meaning of Omkara, with which the Upanishad commenced. This Om, which is All, the all-comprehensive. Name designates this All, which is the Atman. The Atman is the designated; Om, Pranava, is the designator.
Source: The Transcendent Presence - Mandukya Upanishad
We have made an analysis of the three relativistic phases of the Atman, both in its individual and cosmic aspects. But, Reality, as such, is neither individual nor cosmic. To say that it is cosmic is also to limit it to a certain extent, to bring it to the [...]
The third quarter of the Atman, called Prajna, is identified with the third quarter of the Universal Consciousness called Isvara. Isvara is omnipotent and, therefore, He is regarded as the source and the end of all creation. This Prajna is the causal state of the universe, both [...]
Source: Consciousness and Sleep - Mandukya Upanishad
The waking world and the dream world, from the point of view of the Jiva, are two aspects of the function of the mind. The mind projects itself in perception, both in waking and dream. The mind is active, and it gets tired of activity. It ceases from activity [...]
Source: Mystery of Dream and Sleep - Mandukya Upanishad
The first phase of the Atman, as the waking consciousness, has been explained.

This Atman, which is Brahman, is fourfold, and can be approached and attained by a fourfold process of self-transcendence. We now propose to take up these stages, one by one, by way of analysis and synthesis. The first stage of approach, naturally, is that which pertains to the degree [...]
Source: The Individual and the Absolute - Mandukya Upanishad
The first Mantra of the Mandukya Upanishad describes the nature of Omkara and its connotation in relation to the whole universe. Now, it also denotes some object, as was pointed out earlier. It is a Universal Name which refers to a Universal Form in such a manner [...]

The Mandukya Upanishad is attributed to the revelation of a great sage called Manduka. That which pertains to Manduka is Mandukya. The Upanishad or the secret teaching revealed to the sage Manduka is the Mandukya Upanishad. It commences with a solemn declaration:
Om ityetadaksharam idam sarvam, tasyopavyakhyanam bhutam bhavat bhavishyaditi sarvam omkara eva.
The Imperishable is OM, [...]
Three mātrās
There are three mātrās in the word aum : ‘a’ as the ‘u’ in ‘but’; ‘u’ as the ‘u’ in ‘put’; and the ‘m’. The term mātrā is used for the upper limb of Nagari characters and a syllabic instant in prosody. Esoterically, the ‘a’ stands for the first stage of wakefulness, where we [...]
