a riddle...what am I?

What am I?
I am so essential to being human, a sense of me comes preinstalled. I am not and cannot be provided by any other human. I cost nothing and cannot be bought. I am available in any and all circumstances. I am a gift. You just need to engage with me. I am essential for proper brain functioning. You may think you see me in the machinations of the world but it is just a pretence of me. Even if you don't know what I am your search for me can become me until you find me. What am I?

human role in correction

When Pistis saw the impiety of the Lord Archon she was filled with anger. Acting in her invisible form, she spoke in this way: "You are mistaken, blind one -- false deity who cannot see. There is an immortal luminous child, the Anthropos, who came into existence before you and who will appear among your spectral forms (plasmata). This luminous child will trample you in scorn just as a potter's clay is pounded (into a lump). And you will sink away to your proper zone, the abyss (of gravity), along with those who belong to your legion.
"For at the consummation of your work, the entire defect [of Archontic illusion] exposed in the light of truth will be abolished, and [that illusion] will be as if it never had been."
-- On the Origin of the World, 103.15-30
