In this section of Chapter 3, Krishna is explaining why even a self-realised person should keep acting. Here he gives his most powerful social argument: the behaviour of the great and respected sets the standard that everyone else follows. 'Yad yad acharati shreshthah' — whatever a great person does, 'tat tad eva itaro janah' — exactly that the common people do. 'Sa yat pramanam kurute' — whatever standard he sets, 'lokas tad anuvartate' — the world follows it. The word 'shreshtha' means the best, the foremost, the leader — anyone others look up to. Krishna's point is that such a person is never acting in private; their conduct is always teaching, whether they intend it or not. People imitate far more than they obey. We absorb how respected people actually behave, not the rules they recite. So the leader who cuts a corner quietly licenses thousands to cut the same corner. This is the basis of the principle of 'leading by example' (and Krishna applies it to himself in the surrounding verses: though he has nothing to gain, he keeps working, lest people use his inaction as an excuse). The teaching carries a sober responsibility: influence is not optional for those others admire. Your example is a public act with public consequences, and the higher you stand, the longer the shadow your conduct casts.

This is the original 'lead by example' principle, and it explains why role models matter so much — for better and worse. People copy what respected figures actually do, not what they preach. A manager who answers emails at midnight silently makes it the team norm; a parent who is glued to their phone can't lecture their kids off screens; a creator with influence sets trends by behaviour, not captions. The sobering modern application is that influence is now massively distributed — anyone with a following is a 'shreshtha' to someone. Your visible choices ripple outward whether you mean them to or not. The empowering side: you can use this consciously. Want a kinder team, a calmer home, a better culture? You don't have to announce it — you embody it, and people quietly fall in line with what they see modelled. The verse asks the respected to take their example seriously, because the most powerful thing you broadcast is not your opinions but your conduct.

This is 'lead by example' before it was a LinkedIn cliché — and it's really about how influence actually works. People don't do what you say; they copy what you do. Krishna's point: whoever others look up to is constantly teaching by behaviour, on or off. And here's the 2024 upgrade — influence is decentralised now. If even a handful of people watch you, you're a 'shreshtha' to someone, and your visible choices set a quiet standard. The friend who's chill about grades makes the group chill; the one who's always anxious-flexing makes everyone compare. The flip side is a low-key superpower: you can change a vibe without preaching, just by being the example. Want better energy around you? Don't post about it — model it. People fall in line with what they see, not what they're told.

Krishna shares an important truth: people copy what leaders and big people do. If an older kid you admire is kind and works hard, others want to be kind and work hard too. But if they behave badly, others copy that as well. This means whenever you do something good — sharing, telling the truth, helping a friend — you might be teaching someone else to do good without even knowing it. Being a good example is a quiet way of making the whole world a little better!
