Karika 14

अविवेक्यादेस्सिद्धिस्त्रैगुण्यात्तद्विपर्ययाभावात्। कारणगुणात्मकत्वात्कार्यस्याव्यक्तमपि सिद्धम् ॥१४॥

In the unintelligent body, achievements arise from the three qualities because of their deficiency and opposing nature. Thus, qualities are the cause of activities. Hence, the un-manifest nature of the soul is established.
