Verse 15

धैर्येणाभ्युद्धरेद्बुद्धिं पङ्कान्मुग्धगवीमिव ।तामसीं राजसीं चैव जातिमन्यामपि श्रितः

In plain words

By steadfastness one should draw the buddhi up out of the mire, as a bewildered cow is drawn up from it -- even one who has taken refuge in a tāmasika or a rājasika kind, or in any other kind.
