Again the brain is not concerned.
Probably, even in the first deliberate grasping of an object, the brain is not concerned.

Not until there is an element of recognition and sensation-memory.
All our primal activity originates and circulates purely in the four great nerve centers.

All our active desire, our genuine impulse, our love, our hope, our yearning, everything originates mysteriously at these four great centers or well-heads of our existence: everything vital and dynamic.

The mind can only register that which results from the emanation of the dynamic impulse and the collision or communion of this impulse with its object.
So now we see that we can never know ourselves.

Knowledge is to consciousness what the signpost is to the traveler: just an indication of the way which has been traveled before.
