2. Brahmam as Consciousness or Intelligence-10.
The knower of sense-perceptions cannot be the mind, too, though the mind is able to know without the help of the senses and is able to coordinate, arrange, and systematically synthesise sense-perceptions.
Thoughts differ in different places, times and conditions.
Hence, there must be some other synthesising agent of even mental cognitions.
Otherwise a person cannot know that he is the same individual experiencing different kinds of thought.
Even memory would be impossible but for a non-relative consciousness transcending thoughts.
Mental cognitions and sensuous perceptions are heterogeneous in their nature.
Therefore the possibility and experience of a unified completeness of self-identical, absolutely immediate and direct consciousness shows that the true Self is Pure Consciousness in its essence, which is not affected by the revolting activities of the mind and the senses.
The essential nature of the Knower or the Self must be transcendental consciousness, because, in the state of deep sleep it is seen that when the body, the vital currents, the senses, the mind, the intellect, the ego, the subconscious and everything that goes to make the individual get suspended and denied their validity as existence, the person still exists, as is testified by the following experience which, with great certainty, identifies the person who has woken up with the person who slept previously.
