Acharya Prashant explains that the purpose of life is not a matter of opinion or a debate between different philosophies like Hegel versus Vedanta, but a matter of reality. He states that the purpose of life is deeply subjective because it concerns the individual subject who feels restless and unfulfilled. We seek a purpose because we do not feel alright as we are; there is a sense of incompleteness or a 'gaping hole' within us that drives us to seek fulfillment through various means such as power, knowledge, money, or prestige. However, these external pursuits do not bring an end to desire, as the hunger for more power or more knowledge remains insatiable.
