यस्तु विज्ञानवान्भवति समनस्कः सदा शुचिः ।

8. But he, who knows, who has his mind always under control and who is clean, reaches that goal from which he is not born again.

Shankara’s Commentary:

But the second, i.e., the lord of the chariot who has a discriminating intellect as his driver, i.e., the knowing man, having his mind under control and being, therefore, always clean, reaches that goal from which never falling, he is not born again in Samsara.
