Acharya Prashant addresses the concern of living without the ego in a world that seems to demand its protection. He explains that while physical objects, bodies, and systems are prone to destruction and require care, the ego's attempt to protect them is rooted in insecurity, tension, and fear. He distinguishes between things that can be destroyed, such as forms and names, and that which cannot be destroyed, which he likens to space or silence. Living attached to destructible things leads to constant anxiety, whereas identifying with the indestructible 'space' allows for true carefreeness.
