6.28.76

tattadeva prayātyāśu mūḍhānāṃ viparītatām .
dveṣadoṣormiruddhāsu na guṇāścittavṛttiṣu .. 76

76. [Sanskrit available] Whatever a man endeavours to do, with his mind freed from his fondness for or hatred to it, the same comes shortly, to take place, contrary to the attempts of the ignorant: (whose excessive desire and dislike turn to their disadvantage).

77. [Sanskrit available] No good quality can have its abode in the heart that is troubled by the waves of faults; as no stag will set its foot on the ground, heated by burning sands and wild fires.
