Meditation or yoga is first giving reality to thought and then trying to transcend it. Enlightenment or gnana is, not giving any reality at all to thought in the first place.
But this is still versed in a Spiritual mode, still conventional in its estimation.
Enlightenment only occurs from the conventional orientation upon objects. And meditation is a conventional effort of aligning or otherwise correcting the conventional situation through more conventional estimations, of the attempt for more correctly situated True Objects.
