Acharya Prashant explains that the purpose of human life is not merely to pass time or complete a lifespan, as even a person in a coma can survive for decades. True purpose involves struggle and meaning, which distinguishes human existence from mere biological survival. He critiques two common approaches to life: blind faith and science. Faith is often rooted in fear and laziness, where individuals accept pre-packaged beliefs without inquiry. Science, while valuable for understanding the external world, remains incomplete because it ignores the 'observer' or the ego. He emphasizes that Vedanta offers a third path—discernment—which requires investigating both the external world and the internal self, as they are two sides of the same coin.
