Acharya Prashant explains that the mind often experiences frequent and prolonged periods of depression because it consistently makes poor deals. He describes the mind as a trader that attempts to give away its essence—such as freedom, love, and sincerity—in exchange for external gains like acceptance, pleasure, and security. However, this trade is impossible because one's true nature is freedom and cannot be discarded. When a person tries to live as a slave to external desires while remaining inherently free, a dissonance is created that results in suffering. Furthermore, the speaker points out that the rewards the mind seeks, such as pleasure and satisfaction, are fleeting and never truly fulfill the individual. This leads to a state of double loss: the essential nature cannot be traded away, and the desired external gains prove worthless. Acharya Prashant emphasizes that depression is the result of setting wrong priorities where truth and freedom are ignored in favor of status and money. He concludes that true height is found only in the self, and a life not centered on this essence will inevitably feel 'down' or depressed.
