Verse 4

चित्स्पन्दवपुषस्तस्य स्पन्दस्तस्माच्चिदेव हि ।प्रदेशाद्धनतामेति सौम्योऽब्धिश्चलनादिव

In plain words

Of That, whose very body is the spanda (vibration) of consciousness, the spanda is therefore nothing but consciousness; in a particular region it comes to a state of fullness, as a calm ocean does through motion.
