In Walter Isaacson's "Einstein: His Life and Universe," the author presents a reflective perspective on existence, likening it to a brief and transient visit in an unfamiliar place. This analogy emphasizes the temporary nature of life, suggesting that our time here is limited and often undefined.

Furthermore, Isaacson highlights the difficulties in navigating this life with clarity, as our understanding and awareness are described as merely flickering. This depiction of consciousness underscores the challenges humans face in pursuing their paths amidst uncertainty and complexity, inviting deeper contemplation about the nature of existence.
