To know one's own state is not a simple matter. One cannot look directly at one's own face with one's own eyes, for example. One has no choice but to look at one's reflection in the mirror. Through experience, we come to believe that the image is correct, but that is all.
Understanding our own condition can be quite complex, as it is not something we can observe directly. Just like we cannot see our own face without the aid of a mirror, we rely on external reflections to gain insight into ourselves. This process of self-discovery is indirect, as it requires external perspectives to form a belief about our true state.
Over time, we learn to interpret these reflections and accept them as accurate representations of our identity. However, this reliance on an external image underscores the limitations of self-perception and the potential for distortion, suggesting that we may never fully grasp our own essence without outside validation.
