Bhagavad Gita 3.33

Even the wise man acts in accordance with his nature; indeed, all creatures act according to their natures. What is the use of compulsion then?

सदृशं चेष्टते स्वस्याः प्रकृतेर्ज्ञानवानपि।
प्रकृतिं यान्ति भूतानि निग्रहः किं करिष्यति॥

sadṛśaṃ ceṣṭate svasyāḥ prakṛterjñānavānapi|
prakṛtiṃ yānti bhūtāni nigrahaḥ kiṃ kariṣyati||
