Why do "awakened people" keep changing their names (their external labels)?

Because they begin to re-examine the long-assigned identities and evaluations—expectations from parents, societal titles, roles in relationships, and various external labels.
These names once helped them "live," but may not represent their true selves.
Therefore, changing names becomes a way of self-reconstruction: by replacing titles, they try to strip away the parts that "don't belong to me" and find a more authentic expression of their inner selves.
But this process is unstable; people swing back and forth between denying old identities and trying new definitions, sometimes even unsure how to introduce themselves.
Until one day, they slowly realize that what's important isn't finding a perfect name, but beginning to have the "right to name oneself" and the ability to live out that name.
