Acharya Prashant explains that the true Self or the sense of being is independent of any external labels, roles, or circumstances. He points out that even if one's status as a student or their physical environment is removed, their existence remains. He distinguishes between importance derived from external roles, which is fragile and dependent, and the inherent importance of simply being. The speaker emphasizes that the Self is the primary reality that remains constant while everything else, such as childhood or youth, comes and goes. He describes the Self as the stationary center of all change, the witness who observes the passage of time and circumstances without being altered by them.
