यस्तु विज्ञानवान्भवति समनस्कः सदा शुचिः । स तु तत्पदमाप्नोति यस्माद्भूयो न जायते ॥ ८॥

ॐ

English Translation

But if the buddhi, being related to a mind that is restrained, possesses discrimination and therefore always remains pure, then the embodied soul attains that goal from which he is not born again. 

ॐ

English 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 Samsâra.

Sri Shankaracharya
