The examined student is one who has turned the tools of inquiry back upon the inquirer — who studies not only the content of knowledge but the nature of the mind that knows, not only what is learned but how learning itself works and why it sometimes fails. Periagoge names this turning: the rotation of the whole person toward the light of understanding, so that knowledge is not accumulated on the surface of an unchanged self but metabolized into the transformation of the one who is knowing. This is Patanjali's project in four words — yogaś citta-vṛtti-nirodhaḥ — and it is the deepest curriculum any education can offer.
