Acharya Prashant explains that the fundamental human problem is existential, rooted in the ego's tendency to seek security through boundaries and possessions. He describes how the ego mistakenly believes that owning a small, private space is better than belonging to the vast, boundaryless sky. This creates a constant state of restlessness because consciousness naturally resists confinement. To escape this unease, humans often try to fill their lives with external objects and identities, but these only add more layers to the ego and increase dependency. He emphasizes that the solution is not to bring more things inside our walls, but to remove the walls themselves, even though the ego fears this dissolution of its identity.
