Chapter 4: The Nature of Reality : 2.12.
2. Brahmam as Consciousness or Intelligence-12.
As this Consciousness is proved to exist in the deep sleep state also, it is evident that this one Consciousness endures without even the least change in itself in all states of experience, without a past or a future for its existence.
It does not differ from another consciousness, nor does it differ from itself now and then, here and there, in this or that state, as objects and mental states do. Consciousness is always one and is ever secondness.
We cannot conceive of two consciousnesses, though mental states may be two or more. Consciousness is, therefore, eternal. Metaphysically, anything that is eternal must be infinite, without restrictions. Since limitation, too, is what is known by the Consciousness, Consciousness transcends limitation.
The Self is Absolute Consciousness, Brahman or the Bhuma.
The ignorance that is generally experienced in deep sleep cannot be a real existence, for, if it did really exist, it would be an eternal antagonist of consciousness, and consciousness would thereby be limited and become perishable.
The illogicality and the impossibility of the existence of ignorance cancels its value and establishes the existence of the Absolute as Consciousness alone, which is not a bare, featureless transparency, but comprehensive of the whole universe of objects.
Everyone experiences consciousness and not ignorance as his basic being or Self.
The Self is therefore different from ignorance in the sense that consciousness is not ignorance, but it does not mean that the Self is a witness of an objective ignorance, which, too, is existence.
