Shankaracharya's commentary, trans. Alladi Mahadeva Sastry (1897)
[1]Whatever a great man does, that very thing common men do; what standard he sets, by that the people conduct themselves.
BG 3.21
यद्यदाचरति श्रेष्ठस्तत्तदेवेतरो जनः । स यत्प्रमाणं कुरुते लोकस्तदनुवर्तते ॥
yad yad ācarati śreṣṭhas tat tad evetaro janaḥ | sa yat pramāṇaṃ kurute lokas tad anuvartate ||
"Whatever the great one does, others follow. The standard they set — the world adopts. Lead by example."

Whatever a great man does, that very thing common men do; what standard he sets, by that the people conduct themselves.
Whatsoever a great man does, that other men also do; the standard he sets up, by that the people go.
Whatever is done by the great man, that alone others do; whatever standard he sets up, by that the generality of men act.
As the unwise work, so works the wise man, but without desire, And only for the world's good. What the best Doth, that the rest will practise; what he proves, The world will follow.
Whatever a great man does, that other men also do; whatever standard he sets, that the people follow.
