यद्यदाचरति श्रेष्ठस्तत्तदेवेतरो जनः ।
स यत्प्रमाणं कुरुते लोकस्तदनुवर्तते ॥

yad yad ācarati śreṣṭhas tat tad evetaro janaḥ
sa yat pramāṇaṁ kurute lokas tad anuvartate

Whatever action a great man performs, common men follow. And whatever standards he sets by exemplary acts, all the world pursues.

Bhagavad Gita 3.21
