जागरेऽपि धियस्तूष्णीम्भावः शुद्धेन भास्यते ।धीव्यापाराश्च चिद्भास्याश्चिदाभासेन संयुताः ॥ ५ ॥
In plain words
Even while awake, the intellect's very silence is known because pure Cit — pure consciousness — illumines it. Its movements too are revealed by Cit and joined to cidābhāsa, the reflected light of awareness.
Close to the Sanskrit
Even in the waking state, the intellect's condition of silence is illumined by the pure. The operations of the intellect are also illumined by Cit — consciousness — and are associated with cidābhāsa, the reflection of Cit.
