Acharya Prashant addresses the dilemma of choosing a career path based on personal interest versus necessity. He explains that the modern obsession with 'interest' or 'passion' is a product of consumerist culture and ego. According to him, interest is a shallow and fickle concept driven by the ego's tendencies, which often lead toward distraction, greed, and prestige. He argues that spirituality teaches us to prioritize 'Dharma' or truth over personal likes and dislikes. If something is beneficial for oneself and humanity, it should be pursued regardless of whether one finds it interesting or difficult. The speaker emphasizes that the ego uses the lack of interest as an excuse to avoid challenges, especially in fields where one has previously struggled, such as mathematics or technology. He asserts that truth and necessity are far superior to personal interest. Living a life based on interest is equivalent to being a slave to one's impulses, whereas living according to Dharma is the path of righteousness. He warns that the market encourages people to follow their interests only to exploit them for profit. Ultimately, he advises that one should not ask if a field is interesting, but rather if it is right and necessary, urging the listener to value sacredness and truth over the ego's preferences.
