Acharya Prashant addresses the fundamental question regarding the purpose of human life by challenging the very concept of 'life' as a mental construct. He explains that while we can point to physical objects like a dog or a wall, 'life' is merely an idea or a span of time. He asserts that reality exists only in the present moment, and since a moment is too brief to contain a result or a goal, it cannot have a purpose in the traditional sense. He suggests that instead of seeking a future outcome like salvation or heaven, one should focus on being fully present and attentive in the current moment.
