Acharya Prashant redefines leadership by challenging the conventional notion that it requires followers. He explains that true leadership is about taking initiative and living one's own life with intelligence, rather than seeking the power to lead others. While a leader's actions might inspire others or mobilize a crowd for a cause like a freedom struggle, the leader remains independent and does not become dependent on the presence or number of followers. If followers do not listen, a true leader continues their work alone, as their leadership is not derived from the validation of a crowd.
