Ashtavakra Gita 18.44 -

We are all born into the world, with a body and senses. We begin to interact with objects, ranging from the minutest to earth, water, air, fire and space! The four bhūtas exist in space. But space does not exist in anything else. Like the very first parents, or their source, that was not born of anyone, it is self-existing.

The senses contacting objects only send electrical pulses to the brain centres. Brain subjectively forms all sensations. Is the experience objective, gross or solely subjective? In evaluating our experiences, none can escape the fact that they are subjective.

The seeker’s intelligence functions on the basis of himself seeking something else. He looks for the Self, as senses look for objects. As he grows, his idea also grows. Sensory objects are gross, distant, visible. For the mind, Self is internal, nearest.

For anyone, himself is not distant; cannot be. Self is not the body, mind, intellect and ego. It is that ultimate source, from which all have come.

The intelligence of the liberated becomes free of all dependences and hence desires as well. It rests in supreme sentience. All relative thoughts and dependences vanish. Self exists by itself. All else are but Self itself, as dream is but the sleeper. It is verily the ineffable cid-ākāśa, sentient space – sovereign, supreme.
