Bhagavad Gita · 3.23

यदि ह्यहं न वर्तेयं जातु कर्मण्यतन्द्रितः।मम वर्त्मानुवर्तन्ते मनुष्याः पार्थ सर्वशः॥

yadi hy ahaṁ na varteyaṁ jātu karmaṇy atandritaḥ mama vartmānuvartante manuṣhyāḥ pārtha sarvaśhaḥ

For if I ever ceased to engage in action vigilantly, O Partha, people would follow my path in every way.
