Verse 12

रूपालोकमनस्कारान्कुर्वन्नपि न किंचन ।ज्ञः करोत्यनुपादेयान्न ज्ञस्यैव हि कर्तृता

In plain words

Though performing acts of attention to form and appearance, the knower does nothing at all; he performs them as things not to be seized upon — for indeed there is no agency at all belonging to the knower.
