Acharya Prashant addresses the fundamental question of what is the best thing to do in life, given its limited duration. He challenges the questioner's underlying assumptions about life, time, and the future. He points out that when we ask what to do 'next', we are assuming that time and the future are real entities, yet we do not truly understand what life or time is. He suggests that instead of worrying about the future, one should investigate the validity of their current perceptions. He explains that our belief in the existence of the world is based entirely on the testimony of our senses and mind, yet we have no independent way to verify if the senses and mind themselves are reliable. Acharya Prashant emphasizes that the deep-seated belief in the reality of the world leads to materialism. He defines Truth as that which does not require a medium, cannot be doubted, and is independent of time, space, and circumstances. Since everything we perceive depends on our senses and mind, it cannot be the absolute Truth. He asserts that the primary purpose of life is to understand what we actually mean when we say 'life'. As one investigates the nature of the world and the mind, their perspective changes. He concludes that interest in the future is directly linked to attachment to the world; once attachment to the world fades, curiosity and anxiety about the future also disappear. The solution lies in observing the world and the mind's dependence on it in the present moment.
