Acharya Prashant explains that the concept of 'interest' is dangerous and misleading because it is rooted in conditioning and past history. He argues that what people call their interest is often just a product of their environment, like a person's preference for a specific sport based on their country. He advises against choosing a career based on interest, as interests are merely layers of mental conditioning and burdens on the mind. Instead, he suggests that the only valid criterion for choosing work, friends, or a place to live is whether it brings peace or increases restlessness. Since human beings are essentially bundles of restlessness, the goal of any action should be to find tranquility. He further elaborates that most actions are driven by greed or fear, which only lead to further agitation. To find true peace, one must learn to act without a motive, cause, or purpose. Acharya Prashant defines a good career as one that a person would be willing to do even if they were not paid, or even if they had to pay to do it. He emphasizes that 'meaningless' or 'causeless' action is the highest form of living. When work is chosen for ambition or profit, it results in frustration and irritability, which people then vent on others. He concludes that work should be like love—done for its own sake, where one can be deeply immersed without seeking external rewards like money or status.
