Chapter 4: The Nature of Reality : 2.
2. Brahmam as Consciousness or Intelligence-11.
The existence of the essential person, the Self, in the condition of deep sleep, was one of awareness of nothing, an awareness together with nothingness, which means mere awareness, as nothingness has no value.
Further, the existence of the experience of the Self is corroborated by the subsequent remembrance of the existence of oneself in deep sleep.
As remembrance is not possible without previous experience, and as experience is never possible without consciousness, we have to conclude that the Self does exist in deep sleep as mere Consciousness.
This Consciousness exists in the waking state as the unchanging basis of the changing mind and the senses. In the dreaming state it exists as the synthesiser of mental functions.
The objects in the waking and the dreaming states differ from one another, but the consciousness of objects is one and the same; it does not differ in relation to objects.
The only difference between the waking and the dreaming states is that in the former experience is the effect of the function of the mind taking the help of the senses, while in the latter experience is the effect of the function of the mind alone.
But, nevertheless, the consciousness is the same, both in the waking and the dreaming states.
