It is Nature which desires such objects as are liked; it is Nature which hates such objects as are disliked. Desire and hatred originate from Nature, like the upward and the downward vital airs when should have entered animate bodies.
अर्थानिष्टान् कामयते स्वभाव: सर्वान् द्वेष्यान् प्रद्विषते स्वभावः। कामद्वेषावुद्भवतः स्वभावात् प्राणापानौ जन्तुदेहान्निवेश्य॥
