In plain words
The intellect serves to determine things. The knower, ever established in his own essential nature, constantly illuminates that intellect—which experiences all objects—by the light of pure consciousness.
Close to the Sanskrit
The intellect should be for ascertainment; that [intellect] illuminating all objects, the knower [manifests] ever by his own nature with light.
