Acharya Prashant explains Shri Krishna's teaching that great men should perform actions for the welfare of the world, as others naturally follow their example. He clarifies that when we admire or idealize someone, we are actually attracted to a specific quality or achievement they possess which we ourselves desire. We often mistake the traveler for the destination, becoming infatuated with the person rather than the truth they represent. If one is truly devoted to a goal like peace, they will only value those who embody that peace. However, without a clear focus on the ultimate goal, one is easily distracted by worldly attractions and false ideals, eventually losing sight of their original purpose.
