Acharya Prashant explains that while the world is in a state of constant change, there exists an unchangeable center within every individual. He uses the analogy of a fan, where the blades and their positions are constantly moving, yet the axis remains stable. Similarly, human life involves continuous changes in thoughts, physical cells, and external circumstances, but the true center—the witness—remains consistent and unaffected by time. This center is the only thing that is truly consistent, unlike the 'false centers' or the ever-shifting contents of the mind like attitudes, emotions, and conscience.
