Acharya Prashant addresses the issue of overthinking and anxiety by explaining that the mind naturally seeks something to occupy itself. When a person lacks a sense of purpose or something truly important in life, the mind becomes a vacuum that is easily invaded by trivial thoughts and random situations. He compares these unimportant thoughts to germs or pathogens that are always present in the environment; one cannot eliminate them, but one can develop 'inner immunity' by prioritizing what is truly worthy. If the mind is not filled with a significant mission or work, it will inevitably waste time on 'nothing in particular.' He emphasizes that immersion in a meaningful task is the best form of meditation and a powerful antidote to mental troubles like depression and anxiety. By being deeply occupied with something beautiful and important, a person leaves 'no vacancy' for fear or self-pity. Acharya Prashant cites the example of Bhagat Singh, who remained so dedicated to his cause and his reading that he had no time for miscellaneous thoughts or fear, even on the eve of his execution. He encourages the audience to find something worth living for early in life to avoid being scattered and to ensure their time is not squandered on the 'dust of time.'
